Question

The density of a fish tank is 0.5 fish over feet cubed . There are 30 fish in the tank. What is the volume of the tank? (1 point) 60 ft3 120 ft3 6 ft3 15 ft3

Answer 1

The correct option is :  $60 ft^3$

Explanation

Suppose, the volume of the fish tank is $V$ ft³

The density of the fish tank is 0.5 fish/ft³. It means, the number of fish in 1 ft³ volume is 0.5

So, the number of fish in $V$ ft³ volume will be: $0.5V$

Given that, there are 30 fish in the tank. So, the equation will be......

$0.5V=30\\ \\ V=\frac{30}{0.5}=60$

Thus, the volume of the tank is 60 ft³
