Hilbert third problem

WebHilbert’s third problem asked to produce two polyhedra of equal volume which are not scissors congruent. In 1901 Dehn showed that a second invariant, now called the Dehn invariant, was preserved under such decompositions, and that this invariant is zero for the cube but nonzero for the regular tetrahedron, thus providing the example Hilbert ...
