Three rectangular prisms have a combined volume of 518 cubic feet. Prism A has one third of the volume of Prism
b. B and C have the same volume. What is the volume of each prism and the work behind it?
A + B + C = 518 ft^3 A = 1/3B, or 3A = B B = C A + B + C = 518 ft^3 1/3B + B + B = 518 7/3B = 518 B = 518×3/7 = 222 ft^3 A = 1/3B = 1/3×222 = 74 ft^3 C = B = 222 ft^3
