C. 1,080in³
D. 3,240​

Answer 1

9514 1404 393

Answer:

A. 360in³

Explanation:

The formula for the volume of a prism is ...

A = Bh . . . . . . B is the base area; h is the height

The formula for the volume of a pyramid is ...

A = (1/3)Bh . . . B is the base area; h is the height

Clearly, the volume of a pyramid is 1/3 that of a prism with the same base area and height.

The pyramid volume is ...

(1/3)(1080 in³) = 360 in³ . . . . matches choice A
