Respuesta :
Density of the tank is 0.27 goldfish per cubic feet.
Population density of the species in water:
- Population density of a species in the water is given by the expression,
Density = [tex]\frac{\text{Number of species in water}}{\text{Volume of water in the tank}}[/tex]
Given in the question,
- Number of goldfish in the tank = 12
- Volume of the tank = 45 cubic feet
Substitute these values in the expression,
Density = [tex]\frac{12}{45}[/tex]
= [tex]\frac{4}{15}[/tex]
= 0.267
≈ 0.27 goldfish per cubic feet
Therefore, density of the tank will be 0.27 goldfish per cubic feet.
