Question

unit exam - 3d figures part 2
find the volume of the square pyramid.
use the formula: v = \frac{bh}{3}
b = area of the square base.
v = ? ft³

Explanation:

Step1: Calculate base - area

The base is a square with side length $s = 6$ ft. The area of a square $B=s^2$, so $B = 6\times6=36$ ft².

Step2: Calculate volume

We know the height $h = 20$ ft and use the volume formula $V=\frac{Bh}{3}$. Substitute $B = 36$ ft² and $h = 20$ ft into the formula: $V=\frac{36\times20}{3}$. First, $36\times20 = 720$, then $\frac{720}{3}=240$ ft³.

Answer:

$240$
