Exercise #1

Look at the cuboid below:

888555121212

What is the volume of the cuboid?

Video Solution

Step-by-Step Solution

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

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

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

V=l×w×h V = l \times w \times h

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

Step 4: Perform the multiplication in stages for clarity:

First, calculate 12×8=96 12 \times 8 = 96

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

Therefore, the volume of the cuboid is 480cm3\mathbf{480 \, \text{cm}^3}.

Exercise #2

Given the cuboid of the figure:

555999444

What is its volume?

Video Solution

Step-by-Step Solution

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 w = 5 and the height h=4 h = 4 . The diagram also indicates the horizontal length (along the base) is l=9 l = 9 .

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

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

Calculating this, we find:
9×5=45,9 \times 5 = 45,
45×4=180.45 \times 4 = 180.

Therefore, the volume of the cuboid is 180180 cubic units.
