c. 6 ft3
d. 15 ft3

Answer 1

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

Answer 2

yes

Answer 3

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.
