Thank you. This has also turned (on a separate, single-purpose blog, for use at school) into two interesting problems for my students — how many cubes are here, if (A) the figure is hollow, so only the visible cubes need be counted, and (B) the figure is filled with tightly-packed unit cubes. I won’t post the answers here, for that would spoil your fun, and that of other readers of my blog, if any of you want to figure it out for yourselves. 🙂
This one is truly mesmerizing!
