you find the area of the coin (pi * radius^2), multiply it by the thickness and find the volume, then divide the litre by the volume of the coin. elementary, my dear

Put water into a container that has the volume marked on the side in mililitres up to one of the marks, but not all the way up. Make sure you have room for your coins. Take the number of coins that you have available and put them in the water.
They will displace their volume in the water. Look at the new level of the water. The difference between the new volume and the old volume is the volume of displacement in mililitres.
Divide this volume by the number of coins. This is the volume of one coin. Then divide 1000 by this single coin volume to determine the number of coins that would fit in a litre.

you can discover the volume of a $2 coin by using a beaker with very small measurements... fill the beaker to a known level... say 100ml with water... add a $2 coin and then see how much the water rises... if it rises to 101.2 ml.... then you know the volume of a $2 coin is 1.2 ml... then figure out how many 1.2ml is in a litre of water... 1Litre = 1000ml...
Does this make sense??

no calc will work. Go to a bank or grocery store, and if youre a teacher or academic, explain your situation. If they do not let you borrow some coins they should be pelted with marshmallows that are on fire.
Or see if someone has done the same thing on google or something, someone has to already have done it.

Figure out how many fit in a milliliter and multiply by a thousand.
