Question 45534: Decreasing cube. Each of the 3 dimensions of a cube with a volume of y³ cubic centimeters is decreased by a whole number of centimeters. If the new volume is y³ - 13y² + 54y – 72 cubic centimeters and the new width is y – 6 centimeters, then what are the new length and height? Please show work and answer. Thank you.

You can put this solution on YOUR website!
(y^3 - 13y^2 + 54y – 72)/(y - 6)
((y - 6)(y^2 - 7y + 12))/(y - 6)
(y - 3)(y - 4) are your new dimensions
