Question

what is the volume of this rectangular pyramid? 63 ft 76 ft 76 ft cubic feet

Explanation:

Step1: Recall volume formula

The volume formula for a rectangular pyramid is $V=\frac{1}{3}Bh$, where $B$ is the base - area and $h$ is the height.

Step2: Calculate the base - area

The base is a rectangle with length $l = 76$ ft and width $w = 76$ ft. So, $B=l\times w=76\times76 = 5776$ square feet.

Step3: Calculate the volume

The height $h = 63$ ft. Substitute $B = 5776$ and $h = 63$ into the volume formula: $V=\frac{1}{3}\times5776\times63$. First, $\frac{1}{3}\times63 = 21$. Then, $V=5776\times21=121296$ cubic feet.

Answer:

$121296$
