Rhode Island has 1,000,000 people within an area of 1000 sq miles.....
1,000,000/1000 = 1000 people per sq mile
Step-by-step explanation:
If Alaska had the same number of people per square mile as Rhode Island, its population would be calculated as 663,000 mi^2 times 1,000 people = 663,000,000 people.
