An analysis of all the possible permutations of where the smaller constituent cubes (often called “cubies”) can end up shows that there are about 43 quintillion — 43,000,000,000,000,000,000 — possible configurations of the Rubik’s Cube.
How many combinations are there in a 10×10 Rubik’s Cube?
There are a 100 squares per face. That means there are 6100 permutations per face. Multiplied by the six faces of the cube gives an upper bound of 6600 possibilities.
How many combinations are there in a 5×5 Rubik’s Cube?
As if that’s not enough, the 5x5x5 Rubik’s cube (called the Professor’s Cube) has 282 870 942 277 741 856 536 180 333 107 150 328 293 127 731 985 672 134 721 536 000 000 000 000 000 combinations (aka 283 trevigintillion). This is getting uncomfortably close to the number of atoms in the known universe.
How do you figure out the number of combinations in a Rubik’s Cube?
Therefore, the total number of possible permutations of the Rubik’s cube is: (1/2) * (8! x 3⁷) * (12! x 2¹¹) = 43,252,003,274,489,856,000.
What is this number 43252003274489856000?
43,252,003,274,489,856,000 is the number of possible legal arrangements of a standard 3×3×3 Rubik’s Cube. This number is a bit over three dozen quintillion.
What is the biggest Rubik’s Cube?
Guinness World Records has certified the largest Rubik’s Cube in the world at the NINA MALL in Hong Kong. At 2.503 meters x 2.505 meters x 2.502 meters, it officially became the largest Rubik’s Cube on March 28.
Is Rubix cube math?
Mathematically the Rubik’s Cube is a permutation group. In math a permutation group is a group whose elements are permutations of ordered list, and whose group operation is the permutations which rearrange the set in a certain way. The group of all permutations of a set is the symmetric group.
Is there an unsolvable Rubik’s cube?
Most of the times, the Rubik’s Cube becomes unsolvable because someone, intentionally or unintentionally, takes one or more pieces out of the cube. If the piece is now put back in the cube in a different position or orientation, the cube will now be impossible to solve.

How many Rubik’s cubes have been sold?

How many cubes are there in a 3×3 Rubik’s Cube?
Each face has 9 colored tiles in a 3 by 3 arrangement. The Cube appears to be made up of 27 smaller cubes (8 corner cubes, 12 edge cubes, 6 more cubes–one in the center of each face, and 1 cube (which doesn’t actually exist) in the center of the Rubik Cube).
How many ways are there to solve a 3×3 Rubik’s Cube?
“There are more than 43 quintillion ways to scramble a Rubik’s cube,” says computer scientist Tom Rokicki. “That’s more positions than there are grains of sand on all of Earth’s beaches.” Forty-three quintillion—43,252,003,274,489,856,000 to be exact—is the kind of number that defies analysis.
What is after a trillion?
After a billion, of course, is trillion. Then comes quadrillion, quintrillion, sextillion, septillion, octillion, nonillion, and decillion.
What number is the highest?
The biggest number referred to regularly is a googolplex (10googol), which works out as 1010^100. To show how ridiculous that number is, mathematician Wolfgang H Nitsche started releasing editions of a book trying to write it down.

IS 675 a perfect cube?
Grouping the prime factors of 675 to triples, we are left over with 5 × 5. ∴ 675 is not a perfect cube.
Is Rubik’s cube hard?
But it’s not just me — solving a Rubik’s cube is actually really hard. According to mathematicians, solving a cube is considered NP complete. In simple terms, this means Rubik’s cubes are extremely difficult to solve mathematically. It even took Erno Rubik, the inventor of the cube, a month to solve his own cube.
Who is the best Rubik’s Cube solver?
Feliks Zemdegs achieves fastest time to solve a Rubik’s Cube in 4.22 seconds | Guinness World Records.
What’s the hardest Rubik’s Cube?
1. The Pentamix may be the hardest take on Ernő Rubik’s Cube. This Pentamix is certainly a sight to behold. It is considered to be one of the hardest Rubik’s cubes to solve.
Why is my Rubik’s Cube so stiff?
The cube can feel stiff at first after adding lubricant, but after a few minutes of working it in, you should notice faster, smoother turns. If you adjusted the screws, it can take a couple hours of use to break in the cube and check whether the tension is where you want it.
