Question

In a recent year, the population of California was about 252 x 10^6 people. Its land area is about 405 x 10^3 km². What was the average number of people per square kilometer?

Answer 1

To calculate California's population density, divide its population (252 x 10^6 people) by its land area (405 x 10^3 km²), which results in approximately 622.22 people per square kilometer.

Step-by-step explanation:

The question is about determining the population density of California given its population and land area. To calculate the population density, you divide the population by the land area. In this case, California's population is given as 252 x 106 people and its land area is 405 x 103 km2.

Here's the step-by-step calculation:

1. Start with the population: 252 x 106 people.
2. Divide by the land area: 405 x 103 km2.
3. Perform the division: population density = (252 x 106) / (405 x 103).
4. Cancel out the powers of 10: population density = (252/405) x 103.
5. Calculate the resulting fraction: population density ≈ 622.22 people per km2.

Therefore, the average number of people per square kilometer in California is approximately 622.22.
