Question

What is the volume of the square pyramid shown below?

Answer 1

Answer: C) $147cm^{3}$

Step-by-step explanation:

First we need to calculate the area of the square base.

This is 7*7 which equals 49 cm squared.

Plug this value into the formula of a square pyramid which will be $V = 49 * \frac{h}{3}$, now plug in the h, which is 9 cm.

$V = 49 * \frac{9}{3}$

Now solve.

V = 147 cubic cm.
