Today, we learned how big 100 million is. This concept is very vague to me. Although I know that 100 million is very big, I don't know how big it is, so I did an experiment: measuring the thickness of 100 million pieces of paper.

Ten pieces of paper are about 1mm thick, and 1000000000 pieces of paper are100000000 pieces of paper are 100000000mm thick, that is,10000000 meters thick! The height of Mount Everest is more than 8000 meters, and 100 million pieces of paper are higher than Mount Everest! You can imagine what a huge number 1 100 million is!
