Took me a moment. Interesting! So you're saying: Divide the pyramid into very thin slices, parallel to the base (horizontal). Above each slice, insert a duplicate of that slice. If using infinitely small slices, you have effectively doubled the height of the pyramid, and obviously you have doubled its volume. Yes, that makes sense, and I think it's very clever! Thank you.
