An OPEN box has a square base and a volume of 108 cubic inches and is constructed from a tin sheet. Find the dimensions of the box, assuming a minimum amount of material is used in it's construction. HINT: the goal is to minimize the surface are of the OPEN box; this is the function that needs to be minimized. Express the function as a function of one variable using the fact that the volume is 108 cubic inches.
