A rectangular box has a length of (x + 6) inches, width of (x - 2) inches, and a height of (x - 1) inches. a) write a polynomial that represents the volume of the box. b) the volume of the box is 60 inches. Find the height, width, and length of the box. For a, I got x^(3) + 3x^(2) - 16x +12. I need help with b.

your 1st part is correct for 2nd part you equate volume expression to 60 so you will get a cubic equation i n x solve it to height,width and length can u solve the cubic equation??
