Step-by-Step Solution

To solve the problem, let's determine the dimensions of the large cuboid:

  • Step 1: Identify the given values: AB=4 AB = 4 , BC=34×AB BC = \frac{3}{4} \times AB , and BE=12×AB BE = \frac{1}{2} \times AB .
  • Step 2: Calculate the dimensions of the cuboid:
    • Since AB=4 AB = 4 , we find BC=34×4=3 BC = \frac{3}{4} \times 4 = 3 .
    • Next, BE=12×4=2 BE = \frac{1}{2} \times 4 = 2 .
  • Step 3: Calculate the volume of the large cuboid using the formula:
    • Volume=AB×BC×BE=4×3×2=24\text{Volume} = AB \times BC \times BE = 4 \times 3 \times 2 = 24.
    • Since the large cuboid is composed of four equal orthohedra, the volume of the entire large cuboid is 4×24=96cm3 4 \times 24 = 96 \, \text{cm}^3 .

So, the volume of the large cuboid is 96cm396 \, \text{cm}^3.

Video Solution

Step-by-Step Solution

Let's solve the problem by calculating the volume of the large cuboid step-by-step:

Step 1: Determine the dimensions of each small orthohedron

  • Given AB=5 AB = 5 and BC=4 BC = 4 , we understand these are the sides of a triangle segment within the cuboid's formation.
  • The problem states DB=13 DB = \frac{1}{3} of the total sum of AB AB and CB CB , which implies CB CB is as large as BC BC .
  • Hence, DB=13(5+4)=13×9=3 DB = \frac{1}{3} (5 + 4) = \frac{1}{3} \times 9 = 3 .
  • This deduction allows us to assume the height of each small orthohedron h=3 h = 3 .

Step 2: Calculating the volume of one small orthohedron

  • Each orthohedron has dimensions: AB=5 AB = 5 , BC=4 BC = 4 , and the height h=3 h = 3 .
  • Therefore, the volume Vsmall V_{\text{small}} is calculated as:
  • Vsmall=AB×BC×h=5×4×3=60 V_{\text{small}} = AB \times BC \times h = 5 \times 4 \times 3 = 60 cm³

Step 3: Calculate the total volume of the large cuboid

  • The large cuboid is composed of 5 such small orthohedra, so:
  • Vlarge=5×Vsmall=5×60=300 V_{\text{large}} = 5 \times V_{\text{small}} = 5 \times 60 = 300 cm³

Thus, the volume of the large cuboid is 300 300 cm³.

Answer

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the volume formula and apply the given dimensions
  • Step 2: Calculate the total volume by considering the number of orthohedra

Let's proceed:

Step 1: For a single orthohedron with dimensions of 5 meters, 6 meters, and 8 meters, the volume is calculated using:

Volume of one orthohedron=5×6×8 \text{Volume of one orthohedron} = 5 \times 6 \times 8

This equates to 5×6=30 5 \times 6 = 30 , and then 30×8=240 30 \times 8 = 240 . Therefore, the volume of one orthohedron is 240cubic meters 240 \, \text{cubic meters} .

Step 2: Since there are five such orthohedra forming the complete body, multiply the volume of one by 5:

Total volume=5×240=1200cubic meters \text{Total volume} = 5 \times 240 = 1200 \, \text{cubic meters}

Thus, the total volume of the created body is 1200cubic meters 1200 \, \text{cubic meters} .

The correct choice that corresponds to this volume is:

  • 1200cubic meters 1200 \, \text{cubic meters}

Therefore, the solution to the problem is 1200 1200 .

Answer

1200 1200

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the volume of a single cuboid using the dimensions provided.
  • Step 2: Multiply the volume of one cuboid by the number of cuboids to find the total volume of the assembled body.

Let's work through each step:

Step 1: The dimensions of the given cuboid are 3 meters, 4 meters, and 7 meters. The volume of this cuboid is calculated using the formula:

Volume of one cuboid=length×width×height=3×4×7 \text{Volume of one cuboid} = \text{length} \times \text{width} \times \text{height} = 3 \times 4 \times 7

Performing the calculation:

3×4=12 3 \times 4 = 12

12×7=84 12 \times 7 = 84

Therefore, the volume of one cuboid is 84 cubic meters 84 \text{ cubic meters} .

Step 2: Since there are three identical cuboids combined to form the body, we multiply the volume of one cuboid by 3:

Total Volume=84×3 \text{Total Volume} = 84 \times 3

Carrying out the multiplication:

84×3=252 84 \times 3 = 252

Therefore, the volume of the created body is 252 cubic meters\text{252 cubic meters}.

Thus, the correct answer is 252 252 , which matches choice 3 in the given options.

Video Solution

Step-by-Step Solution

To solve this problem, we will calculate the volume of each rectangular prism separately and then sum these volumes:

  • Rectangular Prism 1: The prism with a square base has dimensions as follows:
    • Side length of the square base = 5 units
    • Height = 9 units
  • The volume of a rectangular prism with a square base is given by V=side2×height V = \text{side}^2 \times \text{height} .
  • Substituting the given values: V1=52×9=25×9=225 cubic units V_1 = 5^2 \times 9 = 25 \times 9 = 225 \text{ cubic units} .
  • Rectangular Prism 2: The second prism's dimensions:
    • Length = 3 units
    • Width = 2 units
    • Height = 4 units
  • The volume of this rectangular prism is calculated as V=length×width×height V = \text{length} \times \text{width} \times \text{height} .
  • Substituting the given values: V2=3×2×4=24 cubic units V_2 = 3 \times 2 \times 4 = 24 \text{ cubic units} .

Finally, adding the volumes of the two prisms gives us the total volume:

Vtotal=V1+V2=225+24=249 cubic units V_{\text{total}} = V_1 + V_2 = 225 + 24 = 249 \text{ cubic units} .

Therefore, the volume of the new shape is 249 249 cubic units.

The dimensions of a square-based cuboid are 5 by 7 meters.

The shape shown in the diagram is formed by three orthohedra of the same size.

Calculate the volume of the new shape.

555777

Video Solution

Step-by-Step Solution

To solve this problem of calculating the volume of a new shape formed by three identical cuboids, we need to follow these steps:

  • Step 1: Calculate the volume of a single cuboid.
  • Step 2: Multiply the volume of one cuboid by the number of cuboids (three) to get the total volume.

Let's work through these steps:

Step 1: The volume of a single cuboid is calculated using the formula for the volume of a cuboid, which is:
V=length×width×height V = \text{length} \times \text{width} \times \text{height}

Given that the length and width are 55 meters and 77 meters, and assuming the height (expected to be the same as the base's side since it's square-based and not otherwise specified) is another 55, we have:
Vcuboid=5×7×5=175m3 V_{\text{cuboid}} = 5 \times 7 \times 5 = 175 \, \text{m}^3

Step 2: Multiply the volume of one cuboid by three because there are three identical cuboids:
Vtotal=3×175=525m3 V_{\text{total}} = 3 \times 175 = 525 \, \text{m}^3

Therefore, the volume of the new shape is 525m3\mathbf{525} \, \text{m}^3.

The dimensions of a square-based cuboid are 4 and 8 meters.

From two orthohedra of the same size we build the bodand in the drawing.

Find the volume of the created bodand

444888

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Determine individual cuboid dimensions and calculate its volume
  • Step 2: Calculate the cumulative volume resulting from the merger of two identical cuboids

Let's work through these steps:
Step 1: The given dimensions for a square-based cuboid suggest each has a base of 4 meters and a height of 8 meters. Therefore, the volume of one cuboid is determined using the formula: V=4×4×8 V = 4 \times 4 \times 8 .

Calculating this gives: V=128 cubic meters V = 128 \text{ cubic meters} .
Step 2: Since two such cuboids are combined to form the bodand, the total volume is: 2×128=256 cubic meters 2 \times 128 = 256 \text{ cubic meters} .

Therefore, the volume of the created bodand is 256 cubic meters 256 \text{ cubic meters} .

Vsmall=4×2×5=40cm3 V_{\text{small}} = 4 \times 2 \times 5 = 40 \, \text{cm}^3
Step 2: Since there are 5 such smaller cuboids, the total volume for the large cuboid is:
Vlarge=5×40=200cm3 V_{\text{large}} = 5 \times 40 = 200 \, \text{cm}^3

Therefore, the volume of the large cuboid is 200cm3 200 \, \text{cm}^3 .

Video Solution

Step-by-Step Solution

To solve this problem, we need to determine the volume of a small cuboid when given a total volume comprising four such cuboids.

First, let's establish the dimensions of the large cuboid. According to the problem:

  • The length (LL) of the large cuboid is 10cm10 \, \text{cm}.
  • The width (WW) is half the length, so W=102=5cmW = \frac{10}{2} = 5 \, \text{cm}.
  • The height (HH) is 45\frac{4}{5} of the length, so H=45×10=8cmH = \frac{4}{5} \times 10 = 8 \, \text{cm}.

Next, calculate the volume of the large cuboid using the volume formula:

Volume of Large Cuboid=L×W×H=10cm×5cm×8cm=400cm3 \text{Volume of Large Cuboid} = L \times W \times H = 10 \, \text{cm} \times 5 \, \text{cm} \times 8 \, \text{cm} = 400 \, \text{cm}^3

Since the large cuboid is composed of 4 identical smaller cuboids, the volume of each smaller cuboid is:

Volume of Small Cuboid=Volume of Large Cuboid4=400cm34=100cm3 \text{Volume of Small Cuboid} = \frac{\text{Volume of Large Cuboid}}{4} = \frac{400 \, \text{cm}^3}{4} = 100 \, \text{cm}^3

Thus, the volume of one small cuboid is 100cm3100 \, \text{cm}^3.

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the volume of one prism of each type using the formula for volume: Volume=length×width×height \text{Volume} = \text{length} \times \text{width} \times \text{height} .
  • Step 2: Multiply each result by two since two identical prisms form each body.
  • Step 3: Sum the volumes of the two bodies to get the total volume of the combined structure.

Now, let's work through each step:

Step 1: Calculate the volume of Prism 1:
For Prism 1 with dimensions 6m×7m×3m6 \, \text{m} \times 7 \, \text{m} \times 3 \, \text{m}, the volume is:

Volume of one Prism 1=6×7×3=126m3\text{Volume of one Prism 1} = 6 \times 7 \times 3 = 126 \, \text{m}^3.

Step 2: Since the body is made from two Prism 1 structures, multiply by 2:

Total Volume of first body=2×126=252m3\text{Total Volume of first body} = 2 \times 126 = 252 \, \text{m}^3.

Step 3: Calculate the volume of Prism 2:
For Prism 2 with dimensions 3m×5m×4m3 \, \text{m} \times 5 \, \text{m} \times 4 \, \text{m}, the volume is:

Volume of one Prism 2=3×5×4=60m3\text{Volume of one Prism 2} = 3 \times 5 \times 4 = 60 \, \text{m}^3.

Since the second body is made from two Prism 2 structures, multiply by 2:

Total Volume of second body=2×60=120m3\text{Total Volume of second body} = 2 \times 60 = 120 \, \text{m}^3.

Finally, add the two total volumes together to find the volume of the combined structure:

Total Volume=252+120=372m3\text{Total Volume} = 252 + 120 = 372 \, \text{m}^3.

Therefore, the volume of the resulting body is 372m3 372 \, \text{m}^3 .
