Approximately how much is a 10 mile high stack of pennies worth?

A penny is about 1 milimeter thick.

1 mile = 1,609.344 meters = 1,609,344 mm

Multiply 1,609,344 * 10

Convert your answer to dollars.

To calculate the approximate value of a stack of pennies that is 10 miles high, we need to know the thickness of a penny and the number of pennies in a mile.

1. The thickness of a penny: A United States penny has a thickness of approximately 1.55 millimeters or 0.061 inches.

2. The number of pennies in a mile: We need to convert 10 miles to inches by multiplying it by 5,280 (the number of feet in a mile) and then multiplying by 12 (the number of inches in a foot). So, 10 miles is equal to 633,600 inches.

3. The approximate number of pennies in a stack: To find the number of pennies in a 10-mile-high stack, we divide the stack's total height in inches (633,600 inches) by the thickness of a penny (0.061 inches).

Number of pennies = Total height in inches / Thickness of a penny
= 633,600 inches / 0.061 inches
≈ 10,368,852 pennies

4. The worth of the pennies: The face value of a penny is $0.01, so to find the total value of the stack, we multiply the number of pennies by their face value.

Total value = Number of pennies × Face value of a penny
= 10,368,852 pennies × $0.01
= $103,688.52

Therefore, a 10-mile high stack of pennies would be worth approximately $103,688.52.
