Find the volume of the tank:

Volume = 1 x 4 x7 = 28 cubic feet.

Divide number of fish by volume:

18/28 = 9/14 fish per cubic foot.

Answer:

0.643 fish / cubic foot to the nearest thousandth.

Step-by-step explanation:

The volume of the tank = 1 * 4 * 7

= 28 ft^3.

The population density = the number of fish / the volume of the water

= 18/28

= 0.643.
