Tell you what. I'll agree to this when you can tell how to make a square with five blocks. No more, no fewer.
Equally sized and shaped blocks?
Couldn't you just put 4 blocks in a square shape right next to each other, then place the last directly on top of the one of the others. Then when you look from directly above it, it'll look like a square, but there would still be five blocks. That or throw one of the blocks out the window and arrange the others into a square.
...Except it's a polyhedron with eleven faces now.
But I like the second idea.
