Potter's equation is a mathematical formula which computes the number of face cubes in a Rubik's cube of any size.
Equation
For an NxNxN Rubik's cube, the number of face cubes (R) is equal to:
- R(N) = 6*N*(N-2) + 8
Potter’s Equation applies in all cases where N > 1. Obviously, the N = 1 case is trivial, as is the N = 0 case, though actually solving a 0*0*0 Rubic’s Cube presents a number of practical challenges, even for advanced Cubists.
Notes
This equation is in no way related to Harry Potter.
