Answer:

Volume of cube = 2.33 cubic feet

Length of side of cube = 1.325 feet

Step-by-step explanation:

Given

Weight of each sphere = 350 pounds

Density of each concrete = 150 pounds per cubic foot

Volume of cube = 350 pounds / 150 pounds per cubic foot

Volume of cube = 350/150 cubic feet

Volume of cube = 2.33 cubic feet

Length of side of cube = Cubic root of 2.33

Length of side of cube = 1.325 feet
