Volume of a Orthohedron - Examples, Exercises and Solutions

To determine the volume of a cuboid, we apply the formula:

• Step 1: Identify the dimensions of the cuboid:
  • Length ($l$) = 12 cm
  • Width ($w$) = 8 cm
  • Height ($h$) = 5 cm
• Step 2: Apply the volume formula for a cuboid:

The formula to find the volume ($V$) of a cuboid is:

$V = l \times w \times h$

Step 3: Substitute the given dimensions into the formula and calculate: $V = 12 \times 8 \times 5$

Step 4: Perform the multiplication in stages for clarity:

First, calculate $12 \times 8 = 96$

Then multiply the result by 5: $96 \times 5 = 480$

Therefore, the volume of the cuboid is $\mathbf{480 \, \text{cm}^3}$.

To solve this problem, we'll calculate the volume of the cuboid using the given dimensions:

• Step 1: Identify the dimensions
• Step 2: Apply the volume formula for a cuboid
• Step 3: Calculate the volume

Let's work through these steps:

Step 1: From the diagram, we are informed of two dimensions directly: the width $w = 5$ and the height $h = 4$. The diagram also indicates the horizontal length (along the base) is $l = 9$.

Step 2: To find the volume of the cuboid, we use the formula:
$\text{Volume} = \text{length} \times \text{width} \times \text{height}.$

Step 3: Substituting the identified dimensions into the formula, we have:
$\text{Volume} = 9 \times 5 \times 4.$

Calculating this, we find:
$9 \times 5 = 45,$
$45 \times 4 = 180.$

Therefore, the volume of the cuboid is $180$ cubic units.

This corresponds to choice \#4: 180.

The formula to calculate the volume of a cuboid is:

height*length*width

We replace the data in the formula:  

3*5*7

7*5 = 35

35*3 = 105

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

• Step 1: Identify the given dimensions of the cuboid.
• Step 2: Apply the formula for the volume of a cuboid.
• Step 3: Perform the calculation using the known dimensions.

Now, let's work through each step:
Step 1: The problem states that the cuboid has a length of 8 cm, a width of 2 cm, and a height of 4 cm.
Step 2: We will use the volume formula for a cuboid, which is:

$V = \text{length} \times \text{width} \times \text{height}$

Step 3: Substituting the given dimensions into the formula, we have:

$V = 8 \, \text{cm} \times 2 \, \text{cm} \times 4 \, \text{cm}$

Performing the multiplication:

$V = 16 \, \text{cm}^2 \times 4 \, \text{cm} = 64 \, \text{cm}^3$

Therefore, the volume of the cuboid is $64 \, \text{cm}^3$.

To calculate the volume of the cuboid, we apply the formula for the volume of a cuboid:

$V = \text{length} \times \text{width} \times \text{height}$

Given:

• Length = 9 cm
• Width = 4 cm
• Height = 5 cm

Now, substituting the values into the formula:

$V = 9 \times 4 \times 5$

First, multiply 9 and 4:

$9 \times 4 = 36$

Then, multiply the result by 5:

$36 \times 5 = 180$

Therefore, the volume of the cuboid is 180 cm³.

Since this is a multiple-choice question, the correct choice is 4: $\text{180 cm}^3$.

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

• Step 1: Identify the given information
• Step 2: Apply the appropriate formula for volume
• Step 3: Perform the necessary calculations

Now, let's work through each step:

Step 1: The problem gives us the dimensions of a cuboid: length $L = 8 \, \text{cm}$, width $W = 2 \, \text{cm}$, and height $H = 4 \, \text{cm}$.

Step 2: We'll use the formula to calculate the volume of a cuboid: $V = L \times W \times H$.

Step 3: Substitute the given dimensions into the formula: $V = 8 \times 2 \times 4$ Calculate the result: $V = 16 \times 4 = 64$ Thus, the volume of the cuboid is $64 \, \text{cm}^3$.

Therefore, the solution to the problem is $64 \, \text{cm}^3$.

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

• Step 1: Identify the given dimensions: length = 9 cm, width = 4 cm, height = 5 cm.
• Step 2: Apply the formula for the volume of a cuboid, $V = \text{length} \times \text{width} \times \text{height}$.
• Step 3: Calculate the value by substituting the given dimensions into the formula.

Now, let's work through each step:

Step 1: Given dimensions are:
- Length = 9 cm
- Width = 4 cm
- Height = 5 cm

Step 2: Use the formula for the volume of a cuboid:
$V = \text{length} \times \text{width} \times \text{height}$

Step 3: Substitute the values into the formula:
$V = 9 \, \text{cm} \times 4 \, \text{cm} \times 5 \, \text{cm}$

Calculate the product:
$V = 180 \, \text{cm}^3$

Therefore, the volume of the cuboid is $180 \, \text{cm}^3$.

To solve this problem, we need to identify the correct formula for the volume of a cuboid:

A cuboid is defined by three dimensions: length ($l$), width ($w$), and height ($h$). To find the volume of a cuboid, we use the formula:

$V = l \times w \times h$

Given the answer choices:

• Choice 1: $l \times 2 \times w$
• Choice 2: $l \times w \times h$
• Choice 3: $l \times w$
• Choice 4: $w \times h$

The formula for the volume of a cuboid is explicitly listed in Choice 2, which is $l \times w \times h$. This matches the standard mathematical formula for volume.

Thus, the correct answer to the problem is Choice 2: $\text{length } \times \text{width } \times \text{height}$.

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

• Identify the given dimensions of the rectangular prism.
• Use the formula for volume: $V = l \times w \times h$.
• Calculate the volume by plugging in the given values.

Now, let's work through each step:
Step 1: The problem provides the dimensions of the prism: length = 3, width = 8, height = 2.
Step 2: Applying the formula, we have $V = l \times w \times h = 3 \times 8 \times 2$.
Step 3: Performing the multiplication, we obtain $V = 3 \times 8 \times 2 = 24 \times 2 = 48$.

Therefore, the volume of the rectangular prism is $48$.

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

• Step 1: Identify the given dimensions of the prism.
• Step 2: Apply the formula for the volume of a rectangular prism.
• Step 3: Perform the necessary calculations.

Now, let's work through each step:
Step 1: The given dimensions are height $h = 5$, width $w = 4$, and depth $d = 9$.
Step 2: We use the formula for volume $V = h \times w \times d$.
Step 3: Plugging in our values, we have
$V = 5 \times 4 \times 9 = 180$

Therefore, the volume of the rectangular prism is $180$.

To solve this problem, we need to find the volume of the rectangular prism by following these steps:

• Step 1: Identify the given dimensions.
• Step 2: Apply the formula for the volume of a rectangular prism.
• Step 3: Plug in the values and calculate the volume.

Let's proceed with each step:

Step 1: We are given the length = 5 units, width = 8 units, and height = 12 units of the prism.

Step 2: Use the formula for the volume of a rectangular prism:
$\text{Volume} = \text{length} \times \text{width} \times \text{height}$

Step 3: Substitute the given dimensions into the formula:
$\text{Volume} = 5 \times 8 \times 12$

Now, perform the calculation:
$5 \times 8 = 40$
$40 \times 12 = 480$

Thus, the volume of the rectangular prism is $480$ cubic units.

Therefore, the correct choice from the given options, based on this calculation, is Choice 3: $480$.

To calculate the volume of a cuboid, as we mentioned, we need the length, width, and height.

It is important to note that in the exercise we are given the height and the base area of the cuboid.

The base area is actually the area multiplied by the length. That is, it is the data that contains the two pieces of information we are missing.

Therefore, we can calculate the area by height * base area

15*3 = 45

This is the solution!

The formula for the volume of a box is height*length*width

In the specific question, we are given the volume and the height,

and we are looking for the area of the base,

As you will remember, the area is length * width

If we replace all the data in the formula, we see that:

4 * the area of the base = 80

Therefore, if we divide by 4 we see that

Area of the base = 20

To find the value of $X$, we begin by using the formula for the volume of a cuboid, which is given by $V = \text{height} \times \text{depth} \times \text{width}$.

In this problem, the volume $V$ is 90 cubic units, the height is 5 units, and the depth is 3 units. We need to find the width $X$. So, we write the equation:

Simplify the equation:

To solve for $X$, divide both sides of the equation by 15:

Calculating the right-hand side, we find:

Thus, the width of the cuboid, $X$, is 6 units.

The correct answer to the multiple-choice question is choice 4: 6.

Volume formula for a rectangular prism:

Volume = length X width X height

Therefore, first we will place the data we are given into the formula:

45 = 2.5*4*X

We divide both sides of the equation by 2.5:

18=4*X

And now we divide both sides of the equation by 4:

4.5 = X
