Question

Find the volume of a rectangular prism if the length is 2x, the width is 4x2, and the height is 2x^2 + x + 7. Use the formula

V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume.

Answer 1

V= (4x2) x (2x) x (2x^2+x +7)
8 (2x) (2x^2+x+7)
V= 32x^3 +16x ^2 +112 x

You can also factor out an x and a 16
