Question

The density of a fish tank is 0.2fish over feet cubed. There are 8 fish in the tank. What is the volume of the tank?

Answer 1

For this case the density is given by:
 D = fish / volume
 By clearing the volume we have:
 volume = fish / D
 Substituting values:
 volume = (8) / (0.2)
 volume = 40 feet ^ 3
 Answer:
 the volume of the tank is:
 40 ft3
