On what kind of surface would a square wheel function the same as a round wheel?

(In reply to re(4): I dont know why but.... by Dulanjana)

As long as the corners of the square match up with the "valleys" of the surface, the square will "rock" from one valley to the next, and the next face of the square will rock on the next "hump."
