A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of the base of the speaker is 11 square inches.
What is the volume of the speaker in cubic inches?
22 in.3
198 in.3
66 in.3
33 in.3
The volume of a triangular pyramid is given by the formula V = (1/3) * base area * height.
Plugging in the numbers, we get V = (1/3) * 11 * 6 = 22 in^3.
Therefore, the volume of the speaker is 22 cubic inches.
So, the correct answer is 22 in.3.
