Answer:

Volume of square pyramid = 330.24 inches³

Step-by-step explanation:

Question No 20

Base of Square Pyramid = 8 inches

Height of Square Pyramid = 15.5 inches

We need to determine the volume of pyramid.

The formula used is: $Volume\:of\:Square\:Pyramid=a^2\times \frac{h}{3}$

Putting values of base and height of pyramid and finding volume

$Volume\:of\:Square\:Pyramid=a^2\times \frac{h}{3}\\Volume\:of\:Square\:Pyramid=(8)^2\times \frac{15.5}{3}\\Volume\:of\:Square\:Pyramid=64 \times 5.16\\Volume\:of\:Square\:Pyramid=330.24\:inches ^3$

So, Volume of square pyramid = 330.24 inches³
