What is the definition of density of a fish tank? Is it the number of fishes per cubic feet?

OpenStudy (anonymous):

yes

OpenStudy (ranga):

OK. Assume volume of the tank is V. There are 30 fishes in it. So density = Number of fishes / Volume = 30 / V The density of a fish tank is 0.5. So 30 / V = 0.5 Solve for V.
