Question

Find the volume of a rectangular prism if the length is 4x, the width is 5x, and the height is x^2 + x + 2. Use the formula V = l * w * h, where l is length, w is width, and h is height, to find the volume.

A. 20x^3 + 20x^2 + 40x
B. 20x^4 + 20x^3 + 40x^2
C. 20x^4 + x + 29
D. 20x^4 + 9x^3 +18x^2

I think it's D.

Answer 3

Can you tell me how you got D?

Answer 4

(4x * 5x) * x^2 + x + 2
4x^2 + 4x^2 + 8x
5x^2 + 5x^2 + 10x

20x^4 + 20x^2 + 18x^2

Answer 5

From what i am getting, I'd say it's D as well
