For all polyhedra the number of edges is two less than the sum of the number of vertices and faces. This is shown in the formula \(E\) = \(V\) + \(F\) – 2 The flat surface of a cube is a face.

You should be able to complete this step just by playing around with the cube. Make sure that the edges of the cross match the center squares on the adjacent sides. Step 2: Finish First Layer Step ...
