Answer:
Explanation:
The population density is calculated using the formula:
[tex]\text{Population Density=}\frac{\text{Population}}{\text{Volume}}[/tex]Thus, substituting the given values:
[tex]0.5\frac{fish}{ft^3}=\frac{30\text{ fishes}}{\text{Volume}}[/tex]Cross multiply:
[tex]\begin{gathered} \text{Volume}\times0.5=30 \\ \text{Volume}=\frac{30}{0.5} \\ \text{Volume}=60ft^3 \end{gathered}[/tex]The volume of the tank is 60 cubic feet.
