If you take a marker & start from a corner on a cube, what is the maximum number of edges you can trace across if you never trace across the same edge twice, never remove the marker from the cube, & never trace anywhere on the cube, except for the corners & edges?

• 9. Start from any corner. Select any face of the including the corner. Trace out the four edges surrounding the face. The marker reaches the starting point now. Now move to the opposite face through the edge connecting these two faces and passing through the starting point. Now trace out the four edges on that face too. So total = 4+1+4 = 9 edges.

• Maximum number of edges = 9. Start from one corner. Select any face including that corner. Complete a square (4 edges) around the face to reach at the starting corner point . Now, move to the opposite face through the edge joining them and passing through the starting point(1 edge). Now, complete the square of edges around this face(4 edges). Total = 4+1+4 = 9 edges
