Find the volume of a rectangular prism if the length is 4x, the width is 5x, and the height is x2 + x + 2. Use the formula V = 1.w.h, where I is length, w is width, and his

height, to find the volume.
20x3 + 20x2 + 40x
20x4 + 20x3 + 40x2
20x4 + x + 29
20x4 + 9x3 + 18x2

Answer:

That's the second one from the top.

Explanation:

l = 4x

w = 5x

h = x^2 + x + 2

V = L * w * h

V = 4x * 5x * ( x^2 + x + 2 )

V = 20x^2 ( x^2 + x + 2)

V = 20x^4 + 20x^3 + 40x^2
