Any Rubik's Cube can be solved in 20 moves, but it took over 30 years for anyone to figure that out
In 2010, a group of mathematicians used a bank of supercomputers at Google to show any Rubik's Cube could be solved in 20 moves.

Apparently the Rubik's Cube has 27 cubies.![]()

Area. Rubik's Cubes are interesting because the number of cubies is a combination of Surface Area and Area. Surface area for the centers, Area for the Edges/Corners.lol I wonder how did they get that number

The formula for area is L x W x H. 3 x 3 x 3 is 27.But if you count each individual piece(which is what a cubie is), then you get 26

The toy consists of a cube made up of 27 smaller cubes arranged in a 3x3x3 grid with colored stickers on the outer faces of the smaller cubes...
Sorry, I meant volume. What I'm saying is they should've counted cubies, but they instead used volume.They're not talking about area, but the number of cubies. From the article:
There are only 27 "smaller cubes"
3x3x3 === 27Sorry, I meant volume. What I'm saying is they should've counted cubies, but they instead used volume.
absolute genius
My question is how do they always manage to find wierd color schemes. If you go to Amazon or just your local store almost all cubes are normal color scheme.I saw Daryl playing with a cube (wrong colour scheme) in the american office season 4 episode 16
They solve it by peeling the stickersMy question is how do they always manage to find wierd color schemes. If you go to Amazon or just your local store almost all cubes are normal color scheme.
There are probably an awful lot more Rubik's cubes (especially Rubik's brand) that are what you would consider the "wrong color scheme" in the world than you think. Supposedly 200 million Rubik's cubes were sold worldwide from 1980 to 1983. A significant number of those were sold in the US, and I know that a very large percentage of those used the so-called "Japanese color scheme" - both of my original ones from that era have that color scheme, and I have yet to see one from that era that has the "standard color scheme", although I understand they also existed. Considering that also supposedly there are 350 million Rubik's cubes sold, assuming that only half of the original batch of 200 million had the "Japanese color scheme", that would mean that it is somewhat possible that as many as 1 in every 4 official Rubik's cube ever sold might have the "Japanese color scheme".My question is how do they always manage to find wierd color schemes.

I would assume most people would just get a Rubik's Brand.There are probably an awful lot more Rubik's cubes (especially Rubik's brand) that are what you would consider the "wrong color scheme" in the world than you think.

But that's what I'm saying. Possibly 100 million or more of the Rubik's Brand cubes in the world have the "Japanese color scheme", including 2 that I personally own. NEW Rubik's Brand cubes all have the color scheme you're used to. But a very large percentage of the total Rubik's Brand cubes in the world are not new - they are quite old.I would assume most people would just get a Rubik's Brand.
I have a 1980s "Wonderful Puzzler" and it has the normal scheme. Is it from that cube that the standard colour scheme came from?But that's what I'm saying.

I could see where producers of shows might say, "Hey, I have an old Rubik's Cube in my closet - let me go get it and we'll use it for this scene." Then if it's a 1980's Rubik's Brand cube, it's a good chance it's Japanese color scheme.
I have a Yuxin Little Magic from 2020 with the Japanese colour scheme.But that's what I'm saying.
