# of Jelly beans in a 1-liter jar
Emily Oxford and Gunnar Parker
How many cubic centimeters are in a liter jar?
What is the approximate size of a jelly bean?
1.5 cm in diameter
Question involving volume of the liter jar filled with jelly beans
--- Yes, we're going to say approximately 80% of the liter jar is filled with jelly beans, and the rest will be the spaces between them.
Equation for finding the volume of 1 jelly bean:
2 cm x 3 (1.5 cm/2)^2 = 27/8
Number of jelly beans = (.80 x 1,000) (27/8) = Approximately 240 jelly beans
*remember to multiply by 1,000 because there are that many cubic centimeters in 1 liter jar.
