@platkus@mastodon.social we and you are making different assumptions about what constitutes the area of a puzzle. Our question was "how much area does it take to lay out all the pieces in a single layer", while of course in the box they don't need to be in a single layer. In the extreme case, you could stack every piece on top of the others and say the area of an unassembled puzzle is 1 piece. That's fine! Just not what we were trying to figure out.
