A Floating Ball (Posted on 2003-04-04) Difficulty: 4 of 5
A hollow plastic ball floats in a tub of jello (the flavor is irrelevant, but Iíll tell you: itís key lime). The jello sets, and when the ball is removed, the saucer-shaped depression in the jello measures 6cm across and 1cm deep. If the density of the plastic is twice that of jello, what is the average thickness of the plastic shell?
