Geometrically, we define a face as a solid 3-d figure’s flat side. As the name suggests, a Rubik’s cube is a cube, and as such, it has 6 faces, with three of these meeting at each corner or vertex.
The benefit of knowing how many faces the Rubik’s cube has, and its general structure, is that you get to understand how it works, and subsequently find it easier to solve the cube.
Therefore, in this article, we’re going to have a deeper look at the structure of the Rubik’s cube.
What is a Rubik’s cube?
The original Rubik’s cube is just a cube whose edges are around 2.2 inches long. The cube is made of 26 smaller cubes, commonly known as cubies or cubelets. This might intrigue you because if you were to take a full cube and cut it as though you were making a Rubik’s cube, you’d be left with 27 cubelets. So, how is it that the Rubik’s cube has 26 smaller cubes?
Well, the reason is, the Rubik’s cube doesn’t have the very middle piece. In place of the middle piece, the cube has what is called the central mechanism, that helps it turn.
There are 6 faces on the Rubik’s cube, right? That translates to 6 center cubelets (one on each face). These centers are firmly locked to each other with a 6-armed cross, meaning the centers only rotate, without really changing position. This arrangement provides support for the other cubelets.
The center cubies are colored/stickered differently, and the color of each center cubie defines the color of all the other cubies on that side in the solved state. If it’s red, then the entire face is red; if it’s green, the entire face is green, and so on.
There are 6 centers, and thus there are 6 colors on the cube, namely:
On the classic cube as well as most of the cubes being manufactured these days, the color pattern is as follows:
But, that’s not the only color arrangement that exists. There’s also the Japanese color scheme, which is widespread in Japan and America. With this one, white is opposite blue, red is opposite orange, and green is opposite yellow.
Now, let’s look at the edges and the corners.
There are 12 edge pieces on the Rubik’s cube, which occur between every 2 corners. Each edge piece has 2 different colors.
Just like with every other cube, there are 8 corners on the Rubik’s cube, and thus there are 8 corner pieces, each of which has 3 colors.
Frequently Asked Questions (FAQs)
1.How is a stickered cube different from a stickerless Rubik’s cube?
A stickered Rubik’s cube has colored stickers to differentiate the faces, while a stickerless one has its colors built into the plastic.
2.How can I prevent the faces of the Rubik’s cube from getting dirty?
It’s recommended that you keep the cube in a secure box (some cubes come with a storage box). Use a smooth, clean piece of cloth to wipe the cube after use and prior to storage.
3.Are there Rubik’s cubes with more than 6 faces?
The classic cube has 6 faces but there are variations of the cube, such as the pyraminx, which has 4 faces. There are also variations with as much as 10 faces.
The key takeaway is that the number of faces on Rubik’s cube is 6, and that each of these faces has it unique color, which is determined by the cube’s center piece. That, and all the other things we’ve discussed about the Rubik’s cube’s structure, should help you better understand the cube and solve it more efficiently.
