Answer:
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)
