Question 13
Lines are drawn on three faces of a cuboid. The ant starts at the marked corner and moves toward the sugar along drawn lines or the edges, always getting closer to the sugar and farther from its start. How many routes are possible?
Source clarification: “the edges” can be read in two ways. For the intended reference-key interpretation, use only the visible grid network and its boundary edges on the three shown faces. The solution also analyses allowing every cuboid edge.
