Not that any of us would do such a thing, but if we did, and wanted to cut it to 64 separate squares, how many cuts would it take? A single cut goes between any two rows or columns to the other end, cutting the board or part thereof in two. For example the first cut could be between the columns e and f, making two rectangles, A1-E8 and F1-H8. The second would cut one of the pieces in two, so you might end up with, say, A1-E8, F1-H6 and F7-H8. That procedure would be continued until all 64 squares are separate.
