Summary
| Description |
English: Nicolaas De Bruijn's visual proof that a 6x6x6 box cannot be fully filled with 1x2x4 cuboids, drawn by CMG Lee. When the unit cubes are shaded as in the left figure, each cuboid occupies exactly 2 white and 2 black cubes. The coloured outlines show all possible configurations. However, there are more white than black cubes, as in the right figure. |
