**User:** The volume of a rectangular box is found by multiplying its length, width, and height: V = lwh. A certain box has a volume of b3 + 3b2 - 4b - 12. Factor the four-term polynomial to find the dimensions of the box.
Hint: Use factoring by grouping to factor the four term polynomial first.
b - 3; b - 2; b - 2
b + 3; b - 2; b - 2
b + 3; b + 2; b - 2

**Weegy:** x-8=48^1/2
