Puzzle #22: Cutting the Cube

This is a puzzle picked up from one of Martin Gardner collections. Might be just a touch difficult for kids, but worth trying.

A carpenter, working with a buzz saw, wishes to cut a wooden cube, three inches on a side, into 27 one-inch cubes.  He can do this job easily by making six cuts through the cube, keeping the pieces together in the cube shape.  Can he reduce the number of necessary cuts by rearranging the pieces after each cut?  Either show how or prove that it’s impossible.

Happy solving!

    Does not look possible, cube has 6 sides, it will require 6 cuts to get to 27 one inch cubes.
