[Dissecting a cube into smaller cubes, all different, at least according to what I recall from previous postings.] I saw this problem a very long time ago in one of Martin Gardner's mathematical recreations books. Being at home, I could look it up. The proof is described on page 208 of: Martin Gardner, The 2nd Scientific American Book of Mathematical Puzzles and Diversions, Simon and Schuster, New York, 1961. This is in an appendix to a section describing the finding of a solution to the 2 dimensional version. The proof is attributed to the following paper, which I haven't looked at: R. L. Brooks, C. A. B. Smith, A. H. Stone, and W. T. Tutte, The dissection of rectangles into squares, Duke Math. J. 7 (1940), 312-340. ---Chris Phillips
