As of early 2014, the world's population was about 7.2 billion people. The population of the United States was 317 million.

The area of New York City is 305 square miles. If in early 2014 every person in the world moved into New York City, how many square feet of space would each person have? Round your answer to one decimal place. Note: There are 5280 feet in a mile. First determine how many square feet are in a square mile. 5280 times 5280 is 27,878,400 sq feet. So where would I go from there?

So that is 7 200 000 000 people in 27,878,400 square feet

You want to know how many square feet / person. (area divided by number of people)

Just use the units to help you.

27,878,400 / 7200000000 (sqrare feet per person)

Now just do the division

27,878,400 / 7200000000 = 0.003872 square feet/person

For some reason when I put that answer in it's wrong 0.003872 I try rounding to 0.00387 wrong I tried 0.0039 wrong.

I even tried 0.004 all wrong?

Thanks I knew I had to be forgetting something. So I got 0.003872 x 305= 1.18096 it states round one place so 1.18 ft squared per person

P.S. rounding to ONE DECIMAL place would result in 1.2 sq ft per person....
