Final answer:
Denmark has the greatest population density with 124.7 people per square km, and Ghana has the least with 77.2 people per square km, calculated by dividing the population by area.
Step-by-step explanation:
To find out which country has the greatest and least population density, we need to calculate the population density for each country using the data provided. Population density is determined by dividing the population by the land area of the country. Let's calculate the population density using the given data:
Population Density of Indonesia = 203,479,000 people / 1,904,569 square km = approximately 106.8 people per square km.Population Density of Denmark = 5,248,000 people / 42,077 square km = approximately 124.7 people per square km.Population Density of Ghana = 18,339,000 people / 237,533 square km = approximately 77.2 people per square km.
Based on these calculations: Denmark has the greatest population density with about 124.7 people per square km, while Ghana has the least population density with about 77.2 people per square km.
