This may sound dumb, but congrats man, this was the 9000th teaser accepted.

Great one again fishmed, I just thought of cutting a square cheese cake Keep them coming

hey cool, i actually worked it out ! good one !

Unless the slicing goes as far as the middle of the sides. Then the old 12 edges are replaced by the 24 new ones.

I was thinking the same thing as Stil. It was pretty obvious what answer you were looking for, but the wording of the teaser left a number of other possibilites open.

good one ....
