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).

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)
