Find a polynomial expression in terms of x for the volume of the rectangular prism shown.

Answer 1

6x to the power of 3 + x to the power of 2 - 4

Answer 2

V = 6x³ - 21x² - 12x

Explanation:

Volume of a Rectangular Prism: V = lwh

Step 1: Define

l = 3x

w = x - 4

h = 2x + 1

Step 2: Substitute

V = 3x(x - 4)(2x + 1)

Step 3: Expand

V = 3x(2x² - 7x - 4)

V = 6x³ - 21x² - 12x
