A rectangular prism has length x - 2, width 5x, and height x - 4. Write the volume V of the prism as a polynomial in standard form. Use the formula V = lwh

(x-2) (5x) (x-4)

X times 5x = 5x^2

X times x = x^2

X times - 4 = - 4x

-2 times 5x = - 10x

-2 times x = - 2x

-2 times - 4 = 8

5x times x = 5x^2

5x times - 4 = - 20x

(5x^2 + 5x^2 + x^2) = 11x^2

(-4x + - 10x + - 2x + - 20x) = - 36x

8 = 8

11x^2 - 36x + 8
