Answer: C) [tex]147cm^{3}[/tex]
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 [tex]V = 49 * \frac{h}{3}[/tex], now plug in the h, which is 9 cm.
[tex]V = 49 * \frac{9}{3}[/tex]
Now solve.
V = 147 cubic cm.
