Imagine that you had one million brand new one-dollar bills. Make a guess about how much space they would need. Would these bills fit in your wallet? Would they fit in a suitcase? Would they fit in your bedroom? In your house? Come up with a guess about how much space you would need for one million one-dollar bills and explain your reasoning.
How much space do you think 100 one-dollar bills would take?
How many hundreds do you need to make a million?
Your wallet won't stretch that far. Neither will your suitcase.
However, they should fit in any typical bedroom.
