Question

What is the volume of the right prism? A. 1680 in3 B. 3360 in3 C. 1288 in3 D. 1120 in3

Answer 1

The correct answer is A. 1680 in3.

Explanation:

When I took the test I chose B. for my answer and it was wrong. The formula for the volume of a prism is V = Bh. The base on this prism is a triangle.

Answer 2

To solve this question, first we multiply.

Before anything else, we must find the area of the triangle on either side of the prism. The measurements are 24 in. by 7 in., so we do that, which gives us 168 in.²

Then, we multiply this by the base length, which is 20 in.

168x20=3360, so the correct answer is B, 3,360 in³.
