Rubik’s Cube Invention

Did you know that the Rubik’s Cube was originally invented to help explain 3-D geometry? What’s more bizarre is that this cube has 43 quintillion different ways of being arranged. In case you need to see that visually and exactly, that’s 43,252,003,274,489,856,000 different ways. Wow.

I’m not sure if Erno Rubik, the Hungarian architect who invented this masterpiece in 1974 could have predicted that it had that many different arrangements, but it definitely got the attention of many toy-makers, something he hadn’t originally intended. Now, Rubik’s Cube is celebrating its 40th birthday, and is a fun, addictive game to play.

Math

Each side of the cube has 9 squares, and there are 6 sides in total. How do you find the total number of combinations?

If you were to switch the colours of squares on two sides of the cube, would you be able to create the same arrangement of colours as you did with the previous square? Why or why not?

Is there an arrangement or arrangements of colours on the squares that would render the cube unsolvable? How do you know?
