 4.
Marcelos Bezos is now trying to make a pyramid out of 1 billion pennies. How big would that be? Where should be build it?
 5.
Each stack has 13 pennies which is a strange number to choose. Why do you think Marcelo Bezos chose it? (Hint: Not out of superstition.)
 Teacher noteGive groups of students a dollar in pennies. See how fast they can assemble seven stacks of thirteen pennies. Then ask them to use that as a sample to determine how long it would take them to build the entire pyramid.
 6.
How fast could you make the pyramid Marcelos Bezos made?
 7.
How heavy is the pyramid?
 8.
If Bezos now wanted to add more levels to the pyramid, what's the best way for him to do that?

How long did that to create? How much money is there total? Can I get on the Ellen show by doing this for a class project?



Wow. Didn't know there was a video! How much would this be worth if it was made with nickels/dimes/quarters? What would the dimensions be?


Who in the world has enough time to make this? Or in nicer terms, how long did this take?

How many pennies are there total? How much money do you have if you destroy the pyramid?







How long will it take you to build that? And do you have enough money to do it?






































Given a constant rate of building at 2 pennies per second, how long did it take to build the pyramid?
