Question 24
An ant starts at A and travels along the edges of the rectangular prism. It can only go forwards and cannot travel any edge twice. What is the greatest distance it can travel?
Editorial note: “Forwards” means no reversal within an edge and no repeated edge, as in the source solution; it does not require motion in one fixed compass direction.
