your .geo file is OK.
since the characteristic length you use ( 2 ) is larger than the edges of your cube ( 1 ), the default 3D mesher (Delaunay) generates sometimes some very flat tetrahedra. If you want to keep this characteristic length, then you need to optimize the quality of the mesh, or use the Netgen 3D algorithm. In this case, the generated 3D mesh (tetrahedra) is OK.
