Question

What is the volume of the pyramid in the diagram?

Answer 1

Answer

= 25 cm³

Explanation
The volume of regular solid is found by;
Volume = base area × perpendicular height.

For a pyramid;
 volume = 1/3 (base area × perpendicular height)

In the figure shown, perpendicular height is 3 cm.
Base area = length × height
                 =  5 × 5
                 = 25 cm²

Volume = 1/3(25 × 3)
            = 1/3 × 75
            =  25 cm³

Answer 2

The correct answer is:

25 cm³.

Explanation:

To find the volume of a pyramid, use the formula:

V = 1/3Bh, where B is the area of the base and h is the height of the pyramid.

The base of this pyramid is a square with side length 5; its area is

A = 5(5) = 25 cm².

The height of the pyramid is 3. This gives us:

V = 1/3(25)(3) = 1/3(75) = 25 cm³.
