Final answer:
If the entire world's population of 7.4 billion moved into a city with an area of 707 square miles, each person would have approximately 2.7 square feet of space after rounding to one decimal place.
Step-by-step explanation:
The question asks us to calculate how much space each person would have if the entire world's population of 7.4 billion were to move into a city that has an area of 707 square miles. To find the answer, we first need to convert square miles to square feet. Since there are 5,280 feet in a mile, a square mile would be 5,280 feet times 5,280 feet.
Step 1: Calculate the number of square feet in a square mile:
5,280 feet * 5,280 feet = 27,878,400 square feet.
Step 2: Calculate the total square footage for the city:
707 square miles * 27,878,400 square feet per square mile = 19,709,708,800 square feet.
Step 3: Divide the total square footage of the city by the world's population:
19,709,708,800 square feet ÷ 7,400,000,000 people ≈ 2.66335568 square feet per person.
After rounding to one decimal place, each person would have approximately 2.7 square feet of space.
