If a stack of 50 coins fits snugly in the coin wrapper shown, how thick is 1 coin?

Coin wrapper volume = 27,480 mm^3

Coin diameter = 21.18 mm

Given:

The coin wrapper volume = 27,480 mm³.

The coin diameter = 21.18 mm.

There are 50 such coins.

To find:

The thickness (height) of 1 coin.

Solution:

The 50 coins form a cylinder with a volume of 27,480 mm³.

If the diameter is 21.18 mm, the radius of a coin will be mm.

The volume of a cylinder

The volume of all 50 coins is given as 27,480 mm³. We need to determine the height of a single coin.

mm.

So the thickness of 1 coin is 1.5599 mm.
