Approximating Large Numbers

One rule of thumb for estimating crowds is that each person occupies 2.5 square feet. Use this rule to estimate the size of the crowd watching a concert in an area that is 150 feet long and 240 feet wide.

• 156 people

• 35,031 people

• 5,760 people

• 14,400 people

12 people fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 25 feet deep on both sides of the street along a 3-mile section of a parade route. (Hint: 1 mile = 5,280 ft)

• 264,000 people

• 380,160 people

• 158,400 people

• 2,534 people

15 people fit comfortably in a 6 feet by 6 feet area. Use this value to estimate the size of a crowd that is 30 feet deep on both sides of the street along a 2-mile section of a parade route. (Hint: 1mile= 5,280ft)

• 264,000 people

• 132,000 people

• 190,080 people

• 2,534 people

At a recent “Dog walk” at UGA, the crowd was about ½ of a mile long, 6 feet deep on both sides of the street. If we determined that 11 people could fit comfortably in a 5 ft x 5 ft square, how many people were at the “Dog walk”?

• 13939

• 27878

• 6969

• 6970

A football field is 360 feet long and 160 feet wide.  The principal is making an evacuation plan for the school.  How many students can the principal expect to fit on the football field in an emergency?  (Remember the expected floor space a standing person occupies is about 2.5 sq feet)

• 20340
• 20430
• 23040
• 24030
