What is the probability that the outside of this cube is completely black?

Twenty seven identical white cubes are assembled into a single cube,
the outside of which is painted black. The cube is then disassembled
and the smaller cubes are thoroughly shuffled in a bag.

A blindfolded man (who cannot feel the paint) reassembles the pieces
into a cube. What is the probability that the outside of this cube is
completely black?

I think we need to know area of the wall and area of individual cubes to calculate this
