Question

The dimensions for a rectangular prism are x + 7 for the length, x +9 for the width, and x for the height

What is the volume of the prism? Enter your answer as a polynomial in standard form.
The volume of the prism can be expressed as

Answer 1

V =
`x^(3) + 63`

Explanation:

Substitute:

V = lwh

V = (x + 7)(x + 9)(x)

Multiply:

V = (x + 7)(x + 9)(x)

V = x^3 + 63
