Cubes Dissected into Identical Parts

Five simple dissections of a cube into 2 or 4 congruent parts.

The first three dissections are of a cube made up of 8 units - that is a 2x2x2 cube. Each dissected part is made up of 4 cubes. Two of the three parts are mirror images which nest with themselves but not with the part with the other hand. Two additional dissections are of a cube made up of 64 units dissected into 4 parts. OpenSCAD code is included.
