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.
