MC II-B 3D Geometry Problem 16
In the 2×2×2 cubic figure below, if the path is required to be along the surface of the cube, what is the length of the shortest path from point A to B. This length can be expressed in the form K‾‾√ for an integer K. What is K?
I saw the solution, but I am slightly confused as to how we know it is the shortest one
thanks
