A box is contructed out of two different types of metal. The metal for the top and bottom, which are both square, costs $1 per square foot and the metal for the sides costs $3 per square foot. Find the dimensions that minimize cost if the box has a volume of 20 cubic feet. Length of base x = Height of side z= 4.
