An 80-pound bag of concrete mix will yield 0.6 cubic feet of concrete. Each bag costs $4.98. An artist wants to make a concrete sculpture consisting of three cubes, one on top of the other. The cube at the base will be 3 ft x 3 ft x 3 ft. The next cube will be 2 ft x 2 ft x 2 ft. The third cube will be 1 ft x 1 ft x 1 ft.

How much will the materials cost for the sculpture cost?
