Question

The density of a fish tank is 0.4fish over feet cubed. there are 12 fish in the tank. what is the volume of the tank? 3 ft3 30 ft3 48 ft3 96 ft3

Answers

1. The volume of the tank is 25ft³.
Suppose, the volume of the fish tank is v ft³.
According to the given question.
The density(d) of the fish tank is 0.4 fish/ ft³.
And the total number of fish in the tank is, n =  12.
As, we know that the population density (d) of the fish in the tank is the number of fishes (n) in a given volume (v)
So, the volume of of the tank is given by
d = n/v
⇒ 0.5 = 12/v
⇒ v = 12/0.5
⇒ v = 25ft³.
Hence, the volume of the tank is 25ft³.
