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?

ololo11 [35]

Answer: $30\ ft.^3$

Step-by-step explanation:

Given: Density of tank = 0.4 fish over feet cubed.

We know that, $\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Therefore,

$\text{Volume of the tank}=\frac{\text{Mass}}{\text{Density}}\\\\\Rightarrow\ \text{Volume of the tank}=\frac{12}{0.4}\\\\\Rightarrow\ \text{Volume of the tank}=30\ ft.^3$
