Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;

Population density = population (N)/volume

According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;

Population density of the lake = population of shrimps ÷ volume of lake

Population density = 600,000,000 ÷ 480

Population density = 1,250,000 shrimps per m³
