How Much Money Will Fit? \$50,000 \$100,000 \$250,000 \$500,000 \$1,000,000 \$1,500,000 \$2,000,000 \$2,500,000 \$3,000,000 In \$50 bills In \$100 bills Briefcase Dimensions: 18” x 13” 4.5” 45.7 x 33 x 11.4 cm

How Much Money Will Fit? \$100,000 \$250,000 \$500,000 \$1,000,000 \$1,500,000 \$2,000,000 \$3,000,000 In \$50 bills In \$100 bills

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!

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

How Much is 1 Million? Homework:  Choose an item of interest and determine what it would look like to have 1 million of that item.  Examples: How long is 1 million ____; How tall is 1 million _____; How heavy is 1 million _____; bring in 1 million of your item.  Show your work and provide an object of the same scale for reference/perspective  DUE MONDAY, September 15

Fermi Problems Enrico Fermi was famous for rapid estimations that were highly accurate We’re going to learn how to do these on our own!  First, some perspective: the scale of the universethe scale of the universe  Next, an example Fermi estimationexample Now, complete the cool down in your journals – we’ll go over the answer tomorrow in class
