In a chessboard colouring of the " 2-D plane", every black square has an equal number of white and black squares as neighbours-4 (even sharing a single vertex is counted as a neighbour) . If one did a chessboard colouring of the 3-D space, such that it (the 3-D space) is divided into cubes, and for the 2 planes "vertical" and "horizontal" that every cube belongs to , has a chessboard colouring , what is the number of black neighbouring cubes a black cube has?

There are 26 small cubes "touching" the center cube in this 3x3x3 arrangement. All the middle edge cubes are black. All the corner (8) and center (6) cubes are white. There are 12 black cubes "touching" the center cube at their edges. – Steven Perkins · 1 year, 8 months ago
