Question

Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.

Answer 1

Answer given in the photo

Answer 2

The Volume is equal to 2x^3-3x^2+2x-3

Explanation:

Formula for the volume of a rectangular prism is V=WHL

We know that:

W=x-1

L=x+1

H=2x-3

So, V= (x-1)(x-1)(2x-3)

Simplify

(x^2+1)(2x-3)

2x^3-3x^2+2x-3
