2. Rubik's Cube ‘’Magic cube’’

3. The Rubik’s Cube is a 3-D mechanical puzzle Originally called the “Magic Cube”

4. Invited in 1974 by Erno Rubik He was Hungarian sculptor and professor of architecture

5. In a classic Rubik's Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally:  red,  white,  blue,  orange,  green  and yellow)

6. A standard Rubik's cube measures 5.7 cm (approximately 2¼ inches) on each side. The puzzle consists of twenty-six unique miniature cubes, also called “cubies” or “cubelets”

7. How to Solve the Rubik's Cube...with maths ;) 1.Permutations: -The original (3×3×3) Rubik's Cube has eight corners and twelve edges. -There are 8! ways to arrange the corner cubes.

8. Seven can be oriented independently, and the orientation of the eighth depends on the preceding seven, giving 3 7 (2,187) possibilities

9. ... it really know be interesting

10. 2. Centre faces - The original Rubik's Cube had no orientation markings on the centre faces -Therefore solving it does not require any attention to orienting those faces correctly

12. 3. Algorithms In Rubik's cubists' parlance, a memorised sequence of moves that has a desired effect on the cube is called an algorithm.

13. Each method of solving the Rubik's Cube employs its own set of algorithms, together with descriptions of what the effect of the algorithm is, and when it can be used to bring the cube closer to being solved.

14. or you can do that to simply way...

15. ...or ;)

17. Rubik 360 spherical twist of Rubik’s Cube

18. Rubik 360 The new Rubik’s 360 is a series of 3 nested transparent spheres which feature six coloured balls in the centre of the spheres.

19. the goal of the Rubik’s 360 is to move the coloured balls from the inner sphere to matching slots on the outer sphere by shaking them through a middle sphere, it certainly sounds complicated
