The volume of a fish tank is 50 cubic feet. If the density is 0.5 fish over feet cubed, how many fish are in the tank?

Solution:

Given volume of fish tank = 50 cubic feet

Density = 0.5 fish over feet cubed

Density can be defined as the ratio of mass per unit volume

We  know density = number/ volume

 Number of fishes = density × volume

 = 0.5 × 50

 = 5 × 5

 = 25

The volume of a fish tank is 50 cubic feet. If the density is 0.5 fish over feet cubed, how many fish are in the tank?

Summary:

Thus, if the volume of a fish tank is 30 cubic feet and the density is 0.3 fish over feet cubed then the number of fish is 25
