Hmmm... not to take issue with your son [grin], but these pieces which
form a 3x3x3 Soma Cube do not reform to construct 2 smaller cubes.
In fact, it is impossible for any number of cubic block pieces that form
a single
cube to be able to form two smaller cubes.
This is a corollary of the famous Mathematical theorem known as Fermat's
Last Theorem (which, though it says much more than this, in this case
boils down to the fact that any (positive) Cubed Number cannot be the
sum of two (positive) Cubes).
anyway... the puzzle is still fun.

| (...) lol Okay, I just asked my son for clarification: Me:"Didn't you say that all of these cubes form 1 big 4x4 cube, and also 2 3x3 cubes?" Him: "No. Duh." (but I was told that they do form 2 3x3 cubes but with a few parts left over) Apparently I (...) (23 years ago, 6-Dec-01, to lugnet.build)

| (...) What if you used partly hollow cubes? Two 4x4x4 cubes (one with empty space, one with two empty spaces) could potentially form 1 5x5x5 cube. Cheers Richie (23 years ago, 6-Dec-01, to lugnet.build)
