Answer:
288 cubic ft look at explanation, please give me a thanks if this answer helped!
Step-by-step explanation:
The volume of a pyramid is equal to to 1/3 bh
so first you would find the base which is the rectangle at the bottom
Base= 9 x 8= 72
height has already been given- 12
now your equation is 12 x 1/3 x 72
you can simplify 12 and 1/3 to 4
so now you would have 72 times 4
which is 288
