How much is a billion?
1,000,018,176 pennies - one billion, eighteen thousand, one hundred and seventy-six Pennies take up the space of about five school buses.
Each of these blocks represents one 9x11x41 foot school bus - as seen below. If you were to stack all these pennies in a single pile, one atop the other, the stack would reach nearly one thousand miles high. For comparison, note that the Space Shuttle typically orbits only 225 miles above the Earth's surface.
And this is just pennies not dollars!
