Marbles in the jar and real amount calculation.
It s why you can t just divide the volume of a jar by the volume of a sweet to get the number of sweets in the jar.
This is the volume of the empty space in the jar.
So what does all this mean.
This is a big problem for guessing sweets in a jar.
As you take one marble out of the jar each week the marbles begin going down you see what you have left you get the idea.
If you were figuring how many 5 8 diameter marbles 2 cc each would go into a 1 gallon jar 3785 cc s for example the calculations would be.

2285 12 w 2 14.
Since each marble has volume 2 14 the total number of marbles should then be.
Find the area of the bottom of the jar in item units.
2285 12 the total volume of the jar w.
Creating a behavior marble jar requires little more than a bag of marbles and a few glass jars from your local dollar store or some like these from amazon.
Each child should have their own jar too.
Rotate the jar to see the number of marbles from different sides.

If there are 30 items around the outside of the bottom of the jar divide this number by 6 to get a radius measurement of 5 items.
Pour the water from the jar into the graduated cylinder to find out that you have a volume w of water.
Let s call it 330 plus minus 10.
3785 2 0 6 1324 75 or about 1330 plus minus 10 marbles.
You estimate that there are 48 marbles in a jar.
The larger the jar and or the smaller the marble the higher the density constant would be.
