It is known that for measuring the thickness of thin objects have used devices such as caliper or micrometer. Unfortunately, you don’t have at hand such devices. How do you measure as accurately as possible the thickness of a single coin?

Solution. Posted on Saturday, December 6, 2014.

First of all, you have to sort the coins. Later, stack the coins up at the column and please measure as accurately as possible the thickness of the column. Finally, divide the thickness of the column by the amount of the coins and the result will be the thickness of a single coin.
