Question

The density of a fish tank is 0.3 fish over feet cubed. There are 15 fish in the tank. What is the volume of the tank?

Answer 1

Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given -  (making that a total of 15 grams), 

D = m / v
0.3 = 15 / v 
v = 15 / 0.3 = 50 ft cubed

Hope this answers your question correctly :)
