The density of a fish tank is 0.5 ft³. There are 30 fish in the tank. What is the volume of the tank?
60 ft³, 120 ft³, 6 ft³, 15 ft³

Solution:

Given the density of a fish tank is 0.5 ft³

There are 30 fish in the tank

Density = 0.5 fish over feet cubed

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

We know density = number/ volume

volume = number/density

= 30/0.5

= 30 × 2

= 60

Volume = 60 ft³

The density of a fish tank is 0.5 ft³. There are 30 fish in the tank. What is the volume of the tank?

Summary:

The density of a fish tank is 0.5 ft³. There are 30 fish in the tank, the volume of the tank is 60 ft³
