There are 18 fish in a 1ft x 4 ft x 7 ft. What is the population density in the fish tank? (Round to the nearest hundredth place).

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)
