528 cm^3
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3·Bh
where B is the area of the base and h is the height.
The area of a square of side length s is given by ...
A = s^2
Then the area of the base of the pyramid is ...
A = (12 cm)^2 = 144 cm^2
So, the volume of the pyramid is ...
V = 1/3·(144 cm^2)(11 cm) = 528 cm^3
Answer:
