A Broken Clock Face

While in a museum, an old clock with Roman numerals got cracks on its face, dividing it into 4 parts with unequal totals in each - 17, 20, 20, and 21. If one crack would split one of the Roman numerals it would allow to reach 4 parts with the sum of 20 in each. Can you replicate that number and how the crack should split it?

A Fuse Board into 4 Panels

A half-ready 4x6 fuse board has 4 square apertures in it. Cut it into 4 identical panels, each with one aperture, so that a panel's length is no bigger than the fuse board's width.

A Cube Through Cube

It is possible to cut a hole in one cube to enable another identically-sized cube to pass through it. What would be a shape of the minimal cross-section of such a hole?

Squares-in-Squares

It is possible to draw this shape without: a) taking your pencil off the paper; and b) going over any segment twice. Staring from any outer corner and not counting it as a turn, how many turns will be there in order to get back to the starting point?

Three Squares in One Line

It is possible to draw this shape without: a) taking your pencil off the paper; and b) going over any segment twice. Staring from the top left corner and not counting it as a turn, how many turns will be there in order to get back to the starting point?
