**Reiny**, Tuesday, February 7, 2012 at 11:02pmvolume = length x width x height

so

-x^3 - x^2 + 6x = (length x width) x (2-x)

multiply each side by -1

x^3 + x^2 - 6x = (length x width) x (x-2)

do either a long divsion or use synthetic division to get

x^3 + x^2 - 6x = (x-2)(x^2 + 3x)

= (x-2)(x)(x+3)

so the height is (2-x) , that was given

the length is x+3

the width is x

check:

multiply x(2-x)(x+3) to get -x^3 - x^2 + 6x
