It consists of a solid white cuboid of sides 18 centimetres, 24 centimetres and some other length (which is not a whole number of centimetres). On each face of the cuboid there is a straight red line a whole number of centimetres long going from the mid-point of one edge to the midpoint of another. The six lines together form a continuous route over the surface of the cuboid. The shortest two of the lines are of different lengths. What are the lengths of the six lines? |
