The Soma cube, the Bedlam cube, the Diabolical cube, the Slothouber-Graatsma puzzle, and the Conway puzzle are examples of packing problems based on polycubes.The six pieces are: one dicube, one tricube, one tetracube, one pentacube, one hexacube and one heptacube, that is, polycubes of 2, 3, 4, 5, 6 and 7 cubes.The solution of the SlothouberGraatsma puzzle is straightforward when one realizes that the three 1 1 1 blocks (or the three holes) need to be placed along a body diagonal of the box, as each of the 3 x 3 layers in the various directions.Polycubes are the three-dimensional analogues of the planar polyominoes.We can let them know you were interested.We're sure rslothouber would love a Tip, but unfortunately they have not setup their accounts to receive them yet.Conway puzzle which asks for the packing of eighteen convex rectangular blocks into a 5 x 5 x 5 box.The SlothouberGraatsma puzzle is regarded as the smallest nontrivial 3D packing problem.This follows from parity considerations, because the larger blocks can only fill an even number of the 9 cells in each 3 x 3 layer.1, see also edit, references edit a b, elwyn.There are many similar variations of this type of puzzle, including the Soma cube and the Slothouber-Graatsma puzzle, two other dissections of a 3 3 3 cube into polycubes which use seven and nine pieces respectively.The best known example is the.The, slothouberGraatsma puzzle is a packing problem that calls for packing six 1 2 2 blocks and three 1 1 1 blocks into a 3 3 3 box.The Slothouber-Graatsma puzzle is regarded as the smallest nontrivial 3D packing problem.More general puzzles involving the packing of convex rectangular blocks exist.Like polyominoes, polycubes can be enumerated in two ways, depending on whether chiral pairs of polycubes are counted as one polycube or two.External links edit, retrieved from " ").A harder convex rectangular block packing problem is to pack forty-one 1 x 2 x 4 blocks into a 7 x 7 x 7 box (thereby leaving 15 holes the solution is analogous to the 5x5x5 case, and has three 1x1x5 cuboidal holes in mutually.The Slothouber-Graatsma puzzle is an example of a cube-packing puzzle using convex polycubes.This is analogous to similar insight that facilitates the solution of the simpler Slothouber-Graatsma puzzle.
