Question

Calculate each state’s population density rounded to the nearest whole person. 

New Jersey has an area of 7417 square miles and a population of 9.006 million people. 

The population density of New Jersey is  1214 people per square mile

Alaska has a population of 739,795 people and an area of 571,951 square miles. 

The population density of Alaska is  ?   people square mile 

Then write a sentence explaining how many more people per square mile live in the state with the higher population density than in the state with the lower population density. Use specific state names in your sentence.  

The state of  -?  has  more people per square mile than the state of  ? 

Answer 1

Hi Tonya,

The general formula for density in the scientific context is mass over volume. In this question, population density is defined as the amount of people that live in a given area of land.

In order to find the population density of each state, we must divide the number of people living in that state by the land area of that state. For New Jersey we would divide 9.006 million by 7417 square miles, which yields 1214 people per square mile.

For Alaska we would divide 739795 people by 571951 square miles. That gives just 1.29 people, or 1 person per square mile when rounded.

To put that into a sentence, we would say the state of New Jersey has more people per square mile than the state of Alaska.

Hope this helped,
