Problem M. 328. (December 2012)

M. 328. According to the grandmother of Judy, who always makes chocolate coconut balls for Christmas, if she forms greater balls from the mixture less coconut gratings are needed to roll in the balls. What can the truth behind her opinion be? Look for a theoretical relationship between the size of the balls and the used coconut gratings, and then check it experimentally.
