Question

Find the volume of a pyramid with a square base, where the area of the base is 8.1\text{ ft}^28.1 ft

2
and the height of the pyramid is 9.3\text{ ft}9.3 ft. Round your answer to the nearest tenth of a cubic foot.

Answer 1

`V=25.1\ ft^3`

Explanation:

we know that

The volume of a pyramid is given by the formula

`V=(1)/(3)Bh`

where

B is the area of the base

h is the height of the pyramid

we have

`B=8.1\ ft^2\\h=9.3\ ft`

substitute the given values

`V=(1)/(3)(8.1)(9.3)=25.1\ ft^3`
