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!
The cheapest I saw was at Amazon or at DealExtreme (puzzle cube). You can see cheap rubiks cube for sale at this site cheap http://cheapcuberubiksale.blogspot.com"
Search for a "V-Cube". They make the only 7x7x7cube I know of.

I think there is a such thing as a 7x7 but someone has solved, using a computer program to make it, a 20x20!!!
63
7x7= 49 49-9=40 The answer is 40.
7 x 7 = 49
49
196 98x2=196 49x2=98 7x7=49 2x2&7x7
Start with the 2x2 (easiest). then once you know how to solve it, really well use the 3x3 (Moderate) and the keep going, 4x4(difficult) 5x5(Harder) 6x6(realy hard) 7x7(Really Really Hard). Then see how you do at a Rubik's cube competition. Good Luck,
the 7x7 rule means theres no more then 7 bullets on a slide and no more then 7 sentences on a slide
