Question

The volume of a fish tank is 30 cubic feet. If the density is 0.3fish over feet cubed, how many fish are in the tank?

100
10
9
3

Answer 1

To find the number of fish in the tank, you can use the formula:

\[
\text{Number of fish} = \text{Volume of tank} \times \text{Density of fish}
\]

Given:
- Volume of the tank = 30 cubic feet
- Density of fish = 0.3 fish per cubic foot

Now, plug in the values:

\[
\text{Number of fish} = 30 \, \text{cubic feet} \times 0.3 \, \text{fish/cubic foot}
\]

Calculating this:

\[
\text{Number of fish} = 30 \times 0.3 = 9 \, \text{fish}
\]

Therefore, the number of fish in the tank is **9**.
