The volume of a fish tank is 40 cubic feet. If the density is 0.4 fish over feet cubed, how many fish are in the tank?

Solution:

Given volume of the fish tank is 40 cubic feet

Density is given as 0.4 fish over feet cubed

We know that Density = Mass / volume

Mass = Density × Volume.

Mass = number of fishes in the tank

= 0.4 × 40 = 16

Therefore,

The number of fishes in the tank = 16.

The volume of a fish tank is 40 cubic feet. If the density is 0.4 fish over feet cubed, how many fish are in the tank?

Summary:

If the volume of a fish tank is 40 cubic feet and the density is 0.4 fish over feet cubed, then the number of fishes in the tank is 16.
