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^3Step-by-step explanation:

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
