Monty's Marathon Diary: Wonder Woman Suits Up For One Last Adventure


Recommended Posts

So far as I can tell, each level n has n² tetrahedrons.  The top level has 1, the second level adds 4 more, the third level adds 9 more, etc.  That comes to either 91 (6 levels as shown in the photo) or 140 (7 levels).  If anyone is better at spacial geometry than I am (highly likely) please feel free to correct me.

That's only counting tetrahedrons on the outside, right? If it's solid all the way through, there could be a lot more.

 

Actually, it turns out that I was wrong: you can't evenly divide a tetrahedron into a bunch of smaller tetrahedrons.  I won't pretend to understand the math on that page, and instead will accept it as true since I saw it on the Internet.

 

I've really enjoyed this series, btw!
