To answer this question we must first determine the thickness of a single dollar bill. We can make this measurement with a dial caliper:
With this measuring tool it is easy to determine that a dollar bill is very close to 0.004 inches thick. A stack of one million of these would be 0.004 times 1,000,000 or 4,000 inches tall. To convert inches to feet, divide by 12. 4000 divided by 12 is slightly over 333 feet. Wow, that's more than the length of a football field! A football filed is only 100 yards or 300 feet.
A billion is a thousand million. If a stack of a million dollars is 333 feet high, then a stack one thousand times this would be 333,000 feet. To find how high this is in miles simply divide by 5280, the number of feet in a mile. The answer may surprise you. A stack of a billion one dollar bills would reach over 63 miles high!
Note: Sears Tower in Chicago, Illinois (b. 1974) is 1,454 feet, 443.0 meters, 110 stories.
It is interesting that our space shuttle flies at an altitude of around two-hundred miles above the earth. We would have to stack 3.2 billion dollars to reach this height. Just for fun I looked up NASA's 06 budget. It was fourteen billion dollars. Why, that's only enough money to make four trips. :-)
Prof Aluko,Your computations, which I have not checked, seem to be right on the face of it and I am the one whose numeracy --but not economics-seems 'idiotic'And there you have it--as someone we know would say!Joe
