Euler's polyhedron formula


Euler's polyhedron formula
Leonard Euler was a very famous French mathematician.We researched his theory for part of our homework.We found out that he resurected the theory that if you add the vertices and faces of a 3D shape then minus the edges the answer will always be 2.For example, using a cube, 8 plus 6 minus 12 equals 2.We all found this very interesting.
