An empty sandbox has a length of 6 feet width of 4 feet and a depth of 2 feet. If the sandbox is filled with 8 bags of sand and each bag contains 4.5 cubic feet of sand, what fraction of the sandbox is still empty?

Math 
Ms. Sue,
V = 6 * 4 * 2
V = 48 cubic feet
8 * 4.5 = 36 cubic feet
36/48 = 3/4 is filled
4/4  3/4 = ? empty
