kirill115 [55]

Answer:

The volume of the prism is 300 cubic inches not 300 square inches

Step-by-step explanation:

we know that

The volume of the prism is equal to

where

B is the area of the base

h is the height of the prism

we have

$B=20\ in^2\\h=15\ in$

substitute

$V=20(15)=300\ in^3$

therefore

The volume of the prism is 300 cubic inches not 300 square inches
