You can get them at V-Cubes.com
None! Same amount as in a 7x7x7 hole!!
If you want a 7x7x7 there is only one place to go, http://www.v-cubes.com/ they are the only 6x6x6 and 7x7x7 cubes in the world and they are extremly expencive + a lot of shipping. the 7x7x7 is called a v cube 7
Currently (DEC 09) there are 2x2x2, 3x3x3, 4x4x4, 5x5x5, 6x6x6, 7x7x7, and 9x9x9 mass-produced rubik's cubes. The 6x6x6, and 7x7x7, are available from either V-Cubes (original inventor) or QJ (Chinese Knock-Off), and they both have future plans to make larger ones. QJ has also built a 9x9x9, bu V-Cubes plans to build everything up to 11x11x11, which is so far the only source to publically announce the coming of the 10x10x10. Puzzle-building masters have made their own 8x8x8 (2 in the world), 9x9x9, 11x11x11 (1 in the world, Tony Fisher), and 12x12x12 (1 in the world, Leslie Lee). However, Gabbasoft Cube simulator allows you to solve virtual cubes up to 20x20x20 in size.
5x5x5 gives us 125 7x7x7 gives us 343 343/125 is 2.744
8x8x8 6x6x6
As of mid-2009, nobody's published a working 8x8x8 cube; however, you can buy 6x6x6 and 7x7x7 cubes here: https://v-cubes.com/ecom/home.php?cat=248 You can buy the very playable software at http://www.ganpuzzle.com/vcube888.htm for US$5.95.
6x6x6 rubik's cubes have been released just not by the Rubik's company. You can get them at: DealExtreme.com (type in puzzle cube) V-cube.com (go to V-CUBE Store, six colored cubes, six layers)
You can by them at toysrus or barnes&noble. Hope it help! :>
Some Walgreens, Wal Mart have rubiks cubes avaliable. They are like $8 at Wal-Mart. Highly recommend Cubezz.com - all sorts of Rubik's Cubes can be found in the store, more than 1000+ with freeshipping!
21 Interesting figure, how it was reached I have no idea. However, not including the other products (like the Rubik's magic, and there are lots more) Rubik's or similar companies manufacture - just the Rubik's cube, not including variations on the regular cubes like the Sudokube or special patterned ones, there are four. These include the 2x2x2, the 3x3x3, the 4x4x4 Rubik's, and the 5x5x5. There are 6x6x6 and 7x7x7 cubes in existence, but are technically not Rubik''s cubes because they are manufactured by different companies (Eastsheen, and V-Cube - who are developing cube sizes up to 11x11x11!! (can't wait for that)).
there is a 9x9 rubiks cube but i dont think its possible for a cube to be #x#x# at all
Rubiks Cube, Nissan Cube, Cheddar Cube, and Sugar Cube.
