An ant wants to travel from K to L along the shortest possible route on the surface of the rectangular box shown, whose edges are a,b,c. Find the route length.
Editorial model: The ant may use every exterior face. No inequality between a,b,c is assumed from the sketch. The source restricts its calculation to one face pair.
