Question

Find the volume of the composite figure. Round to the nearest tenth. The base of each pyramid is a square with a side length of 5 inches and each pyramid has a height of 9 inches.

Answer 1

`75` cubic inches

Explanation:

Given:

The base of each pyramid is a square with a side length of 5 inches

Height of of pyramid is 9 inches.

To find: volume of the pyramid

Solution:

As the base of each pyramid is a square with a side length of 5 inches,

length of the pyramid (l) = base of the pyramid (b) = 5 inches

Height of of pyramid (h) = 9 inches

Volume of the pyramid
`(V)=(lbh)/(3)`

On putting values of l, b and h, we get

`V=(5* 5* 9)/(3)=75` cubic inches
