A roll of 50 pennies measures about 3 inches tall and 3/4 of an inch in diameter. In order to have 1,000,000 pennies you would need 20,000 rolls. If you placed them on end, 20 rolls by 20 rolls and stacked all 20,000, you would need to have 50 layers of pennies. This would give you a final dimension of 15 inches by 15 inches by 12 1/2 feet.

The container we will be using is a cube measuring 41 inches in length, width and height and will hold the pennies lose (not rolled).
