Question

find the volume of this rectangular pyramid. be sure to include the correct unit in your answer.

Explanation:

Step1: Find the base - area

The base is a rectangle with length $l = 9$ yd and width $w = 8$ yd. The area of the base $B$ is given by $B=l\times w$.
$B = 9\times8=72$ yd²

Step2: Use the volume formula for a pyramid

The volume formula for a pyramid is $V=\frac{1}{3}Bh$, where $h$ is the height of the pyramid. Here, assume the height of the pyramid is the perpendicular height from the apex to the base. Given the height $h = 9$ yd and $B = 72$ yd².
$V=\frac{1}{3}\times72\times9$
$V = 216$ yd³

Answer:

$216$ yd³
