Question

A stereo speaker in the shape of a triangular pyramid has a height of 8 inches. The area of the base of the speaker is 12 square inches. What is the volume of the speaker in cubic inches?

Answer 1

32 cubic inches

Step-by-step explanation:

pyramid height = 8 inches

The area of the base of the speaker = 12 square inches

Volume of a triangular pyramid = 1/3 × area of base × pyramid height

Volume of a triangular pyramid = 1/3 × 12 × 8 = 96/3

Volume of a triangular pyramid = 32 cubic inches
