Question

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

Explanation:

Step1: Find the base - area of the rectangular base

The base is a rectangle with length $l = 9$ ft and width $w = 6$ ft. The area of a rectangle $A_{base}=l\times w$.
$A_{base}=9\times6 = 54$ ft²

Step2: Use the volume formula for a pyramid

The volume formula for a pyramid is $V=\frac{1}{3}A_{base}h$, where $h = 5$ ft is the height of the pyramid.
$V=\frac{1}{3}\times54\times5$
$V = 90$ ft³

Answer:

$90$ ft³
