Problem Statement

Basil has a melon in a shape of a ball, 2020 in diameter. Using a long knife, Basil makes three mutually perpendicular cuts. Each cut carves a circular segment in a plane of the cut, hh deep (hh is a height of the segment). Does it necessarily follow that the melon breaks into two or more pieces if (a) h=17h = 17 ? (6 points) (b) h=18h = 18 ? (6 points)
