What is the volume of the speaker in cubic inches?
A.20
B.40
C.60
D.80

Answer 1

The correct option is B. 40.

Explanation:

To calculate the volume of a triangular pyramid, you need to know the height and the area of the base. In this case, the height of the triangular pyramid is given as 12 inches, and the area of the base is given as 10 square inches.

The formula for the volume of a triangular pyramid is:

Volume = (1/3) * Base Area * Height

Substituting the given values:

Volume = (1/3) * 10 square inches * 12 inches

Volume = (1/3) * 120 cubic inches

Volume = 40 cubic inches
