box

[lukebray]

does anyone know if it is possible to draw a box with an x inside it without taking ur pen/pencil off the paper and without going over any of your previously drawn lines???

[gen2]

Definitely impossible because there are more than two corners where an odd number of lines meet.

I can remember doing this as a child, many years ago, but the box had a pointed roof and it was possible

[gen2]

Yes FoxLee, that is possible because you have reduced the number of corners where an odd number of lines meet to 2. One will be your starting point and the other your end point.

luke - Are you meaning a square drawn with (two) diagonal lines drawn from corner to corner? Or do you mean a square with a small cross in the middle?

The first problem is NOT possible (as stated by gen2 below), but the second is!

[crofter]

I agree 100% percent with gen2's comment above!

It is possible if you structure the box as a cube essentially extending lines "out of the box" to connect

[charlatan53]

It's a variation of a classic question that connects a nine point square grid with 4 continuous straight lines.
