5. How Tall is $1M? We’ve already figured out how thick any note of U.S. currency is: 0.010922 cm If we stacked 1 million bills on top of each other, how tall would our stack of money be? 109 m (~30 stories!) That’s the length of a football field and more than half the height of the Space Needle!

6. Estimation! 1. How much would 1 million weigh?? 2. Watch video: “How Much Does $1M Weigh?”How Much Does $1M Weigh 3. He estimated that 1 million dollar bills weighs about 900 kg (~2,000 lbs.) 4. How close is he? Let’s find out! 5. So even though estimation is not an “exact science” it is a pretty good tool to use when time is short.
