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

Answer:

$75$ cubic inches

Step-by-step 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 $(V)=\frac{lbh}{3}$

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

$V=\frac{5\times 5\times 9}{3}=75$ cubic inches
