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!
