at olympicube.com they have a release date of September. You can preorder them in June which is in a day. Idk if you will be able to preorder them the first day of June though.
You can get them at V-Cubes.com
5x5x5 gives us 125 7x7x7 gives us 343 343/125 is 2.744
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
When c = the number that is the dimension of the cube (ex. this time, 7), you can find the number of cubes for any size of cube. c3 - (c - 2)3 So for 7, that is 7x7x7 - (5x5x5) 49x7 - 25x5 343 - 125 218 There are 218 cubies in a 7x7x7 Rubik's cube!
343
Right now there are 6, 2x2x2 trough 7x7x7, (though the last 2 weren't made by the rubik's company) Some people say that the 8x8x8 and 9x9x9 are for sale, but I'm not sure.
7x7x7 it will be 7 to the 3rd power . so7to the 3rd power.
Do the math.
The answer equals 343
7x7x7 =343
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.
