A penny is 1.55 millimeters thick. If you stacked $200 worth of pennies on top of each other, how tall would the stack be, in meters?

Height of stack will be 31 meters

Explanation:

Thickness of a penny = 1.55 millimeters

Total stacked amount = $200

Total number of pennies = 200 x 100 ($1=100 pennies)

Total number of pennies = 20,000 pennies

Total height of stack = 20,000 x 1.55 mm

Total height of stack = 31,000 mm

Total height of stack = 31,000 / 1000 (1 m = 1000 mm)

Total height of stack = 31 m
