There are 453.592 grams in a pound, so 10 pounds would be 4535.92 grams. The density of copper, the main component of pennies, is 8.96 grams per cubic centimeter. A penny has a volume of 0.36 cubic centimeters, so 4535.92 grams of pennies would have a volume of 5050.89 cubic centimeters. With 2.5 grams per penny, there would be approximately 2023 pennies in 10 pounds, which would total $20.23.
