Question

Show steps: Find the volume of a rectangular prism with a length of x + 9, a width of x – 7, and a height of x – 1. What is its volume expressed as a polynomial?

Answer 1

Please see attached picture

Explanation:

A rectangular prism has its volume defined as

V_rect_prism = length * height * width

V_rect_prism = (x+9) * (x-1) * (x-7)

The volume expressed as a polynomial can be seen in the picture below.
