    0.23

    Step-by-step explanation:

    Population density is defined ad the ratio of the total density to the area of the tank.

    Total population = 18

    Surface area of the tank = >2 (LW+LH+WH)

    Given length = >1ft

    Width = 4ft

    Height = 7ft

    S = 2 ((1) (4) + 4 (7) + 1 (7))

    S = 2 (4+28+7)

    S = 2 (39)

    S = 78ft²

    Population density = 18/78

    Population Density = 0.23 (to nearest hundredth)
