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?
A) 22 in.3
B) 198 in.3
C) 66 in.3
D) 33 in.3

The correct answer is A. 22 inches ³

Step-by-step explanation:

Let's recall that the formula of the volume of a triangular pyramid:

Volume = 1/3 * Area of the base * height

Replacing with the values we have:

Volume = 1/3 * 11 inches² * 6 inches

Volume = 66/3

Volume = 22 inches ³

The correct answer is A. 22 inches ³

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.
