Obama Inauguration Project
During this problem we were given a satellite picture of Obama's inauguration and we had to measure all the people who were there. We did this by measuring the size of the area in the picture and then finding the area of the National Mall in real life. After this we found a scale and measured the area of the place in real life. Then we found that the average person occupies an area of 2.5 feet squared. We found an equation that told us how many people fit in the area of the National Mall and found that about 1.8 million people were there.
Here are a few steps on how we got our conclusion:
1. Found measurements of the real life National Mall, and other landmarks in the picture, then measured the actual (printed) picture.
2. Created Scale: Scale: 656 ft./2.4 cm. = 273 ft./cm.
3. Figured out the size of a person: People are about 2.5 ft. squared.
4. Measured one of the blobs: 1.5 cm. by 2 cm. -> 1.5*273 by 2*273 -> 409.5 ft. by 546 ft. = 223,587 ft. squared
5. Estimated the amount of people in blob: 223,584/1.5 = 149,058 people in blob
6. Total Estimate: Our estimate: 149,058 people in blob 1 * 10 blobs = 1,490,580 people in all

This is the poster my group made to explain our observations and estimates.
This is the map of the Obama inauguration, and it shows the black spots of people that were at the event.
