Question

The density of a fish tank is 0.4 fish over feet cubed . There are 12 fish in the tank. What is the volume of the tank?

Answer 1

Explanation:

Volume = 30 ft³

density = population/area

.4 = 12/ft³

(.4)(ft³) = 12/ft³ × ft³/1

.4 ft³ = 12

.4ft³ /.4 = 12/.4

ft³ = 30

30 ft³

Answer 2

=30 ft³

Explanation:

From the scenario given the formula for density of the fish pod is

ρ= no. of fish/ volume

Making volume the subject of the formula we obtain the following equation:

Therefore volume = no.of fish/ρ

Using the values provided in the question:

=12 fish/0.4 fish/ft³

=30 ft³

= 4.8
