Question

The width of a rectangular prism is w centimeters. the height is 2 centimeters less than the width. the length is 4 centimeters more than the width. of the volume of the prism is 8 times the measure of the length, find the dimensions of the prism

Answer 1

w x (w-2) = 8
w^2 - 2w = 8
w^2 - 2w - 8 = 0
(w-4)(w+2) = 0

w = 4 Or w = -2

However w cannot be less than 0

So w must = 4

Width is 4, height is 2, length is 8
Total Volume =64 which is 8(8).
