X = total amount of people
80% of x = 540
.8x = 540

Fish tank A
V = Ah = 25 ft^2 * 8 ft = 200 ft^3
Fish tank B
V = Ah = 40 ft^2 * 4 ft = 160 ft^3
The volume of fish tank A is 200 ft^3, and the volume of fish tank B is 160 ft^3, so fish tank A has a greater volume. Its volume is greater by 40 ft^3.
