The challenge is to cover the surface of a cube using hexominoes. If we allow the pieces to bend around the edges, then cubes with non-integer edges can be covered.
Edge Length = 1
Eleven hexominoes can be folded to make a cube with a unit square face. The pieces have been coloured to match the 3D image.
