Question

what is the volume of this rectangular pyramid? 9 in 9 in 12 in cubic inches submit

Explanation:

Step1: Calculate base area

The base is a rectangle with length 12 in and width 9 in.
Base area $B = 12 \times 9 = 108$ square inches.

Step2: Apply volume formula

Volume of pyramid $V = \frac{1}{3}Bh$, where $h = 7$ in.
$V = \frac{1}{3} \times 108 \times 7$

Step3: Compute final volume

$V = 36 \times 7 = 252$

Answer:

252 cubic inches
