What is the volume of the right prism?

748 in^3

1320 in^3

1496 in^3

660 in^3

Step-by-step explanation:

To find the volume of this prism, find the area of the (white) face and then multiply it by the length of the prism.

The face is a triangle with base 8 in and height 15 in.  According to the area-of-a-triangle formula, the area is A = (1/2)(base)(height), which here is:

A = (1/2)(8 in)(15 in) = 60 in^2.

Multiply this by 11 in to get the volume of the prism:  

V = (60 in^2)(11 in) = 660 in^3  (this is the fourth possible answer)
