Today I was given a task to figure out how many jellybeans are in this one jar. I am not allowed to take out the jellybeans inside the jar, I am only allowed to take one jellybean out and weigh it, measure etc. So do you guys have any strategies on figuring out how many jellybeans are in the jar without taking anything out of it? And there is no spare jar to weigh/measure etc. Thank you.

This seems almost impossible to answer!

1) Find the volume of the container using a simple formula.
2) Then FILL the remaining space in the jar with water.
3) Drain the water out of the jar and measure it. Work out the volume of the water.
4) Subtract the water volume from the jar volume.
5) That will give you the volume of the entire jelly beans.
6) Work a single jelly bean volume and away you go...

Try to calculate the volume of a single jellybean, and the volume of the jar. You'll have to also come up with some rationale for a guess at "void volume," that is, the volume of the jar not filled by jellybeans (because they don't fit together perfectly).

Weigh one jelly bean.
Put it back in the jar.
Weigh the whole jar.
Divide the weight of the jar by the weight of the 1 jellybean.
[Subtract about 1-2 lbs for the weight of the jar alone(depending on the size of it)]
You'll be close enough.

find identical jar weigh it weigh jellybean separately and weigh jar with all jellybeans subtract weight of jar and divide by weight of 1 jellybean now you have how many are in the jar

see if the jar has any markings on it's capacity. Once you measure the jelly bean you can divide the capacity by the size of your jelly bean.
The other way would be just to ask the taskgiver if anyone else besides them knows. stuff like that.

There is really no way. But you might ask MONK the detective on USA TV he seems to know answers like that. It's all a matter of chance, if there was a sure way of figuring it out, then it wouldn't be much of a contest.

yeah determine the lenght width and height of one jelly bean in millimeters and then determine the length height and width of the containing space. The total cubic space of the jar divided by the cubic space of one gives you a very accurate approximation.

buy the same jar and fill it up with jellybeans then empty it then count the jellybeans.

Length*Width*Height

u can use the weight of one jelly bean x the weight of the jar
