Ok, it seems to be math puzzle week here so I'm submitting this puzzle which is actually a calcuation problem. 1. I'm make this up as I go so I don't know the answer. 2. There are an unlimited number of non compressable spherical marbles with a diamater of 2 cm. 3. There is a cylinrical container which when closed with a lid has an internal diameter of 10 cm and a height of 13 cm. What is the maximum number of marbles you can actually place inside the container and then place the lid on without distorting the cylinders shape. Please show working as well as answer. :-) Have Fun. Regardz Colin J Davies

Yes whole complete marbles, David. So you are not permitted to pulverize them. :-) Regardz Colin J Davies

This is what I call a math problem. I do not even know if this problem can be solved by mathematical means. I am going to purchase some marbels and make up a cylinder. See you after some time :-)

square area of the base of the cylinder = PI*5*5 = 25*PI square area of the middle cross section of a marble = PI*1*1 = PI no.of marbles that can cover the base =(25*PI) / PI = 25 No. of marbles that can be stacked top to bottom of the cylinder in one column = 13/2 = 6.5 = 6 approx. since half marbles are not allowed total no. marbles = 25 * 6= 150

This sounds like Keplars sphere packing problem from 1609. :eek: Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one.

From how I heard it, it was first posited as "how can you most efficiently stack X number of cannon-balls into the smallest area possible". -- Russell Morris "WOW!
