A box with no top is to be made by cutting a 2inch square from each corner of a square sheet of metal. After bending up the sides, the volume of the box is to be 220 cubic inches. Find The the length of a side of the square sheet of the metal that should be used in the construction of the box. Round to the nearest hundredth. , need equation to solve.

Let L = side length of square sheet.
[(L4)^2]*2 = 220
(L4)^2 = 110
L4 = 10.488
L = 14.488 inch
Rounded: 14.49 inch
