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?

4 ft3
16 ft3
32 ft3
40 ft3

Answer 1

40ft

Explanation:

I took the test

Answer 2

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
