Cube , also known as Rubik box, magic box called Taiwan , Hong Kong, called the Rubik's Cube , the English called : Rubik's Cube. Is an entertaining toy, original E Ernuo Rubik (Ern Rubik) Professor invention cube, just as a way to help students enhance spatial thinking skills teaching tool. But for those little boxes can freely rotate without spread, not only a mechanical problem, which involves the wooden shaft, seat and tenon and so on. Until cube in the hand , he will turn a few cube , only to find how to recover chaotic color box was actually interesting and difficult question . Rubik was determined to mass production of such toys. Cube shortly after the invention swept the world , people find stuff this little box is really composed of infinite mystery .

Changes in the total number of third-order cube is 43,252,003,274,489,856,000. Or approximately equal to 4.3X10 ^ 19. If a second turn 3 next cube, excluding repeat, you need to turn 454.2 billion, the cube can turn out all changes, this figure is the current estimate is about 30 times the age of the universe.
