Question

the volume of a fish tank is 40 cubic feet. if the density is 0.4 fish/feet³, how many fish are in the tank?

Explanation:

Step1: Recall the density - volume - quantity formula

The formula for density $
ho=\frac{n}{V}$, where $
ho$ is density, $n$ is the number of fish, and $V$ is volume. We want to find $n$, and we can re - arrange the formula to $n =
ho\times V$.

Step2: Substitute the given values

We are given that $
ho = 0.4\frac{\text{fish}}{\text{feet}^3}$ and $V = 40\text{ feet}^3$. Then $n=0.4\times40$.

Step3: Calculate the result

$n = 16$.

Answer:

16
