A coin is 1.95 mm thick. How many coins does it take to make a stack that is 5.85 mm tall?
To find out how many coins it takes to make a stack that is 5.85 mm tall, we need to divide the total height of the stack (5.85 mm) by the thickness of a single coin (1.95 mm).
5.85 mm / 1.95 mm = 3
Therefore, it takes 3 coins to make a stack that is 5.85 mm tall.
