Find an algabraic expression for each of the dimensions of a rectangular prism whose volume can be represented by: V=18x^3+39x^2-15x

Answer 1

V=3x(6x^2 +13x-5)= 3x(3x-1)(2x+5)

sides 3x times 3x-1 times 2x+5 = 18x^3 + 39x^2 -15x = Voliume

maybe 3 feet by 2 feet by 7 feet = 42 cubic feet, if x=1

but the dimensions could be most anything, as the volume polynomial doesn't have to so easily factor
