you have to order it online at v-cube's website and then have it shipped here. It takes about a week to a week and a half to get the cube from Greece. I believe i read on the v-cubeFacebookpage that you can buy it from Marbles The Brain Store if you have one by you if not you can also buy them on Ebay and Amazon but be carefula lotof KO's out there.
You can buy the v-cube at www.v-cube.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

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.
The volume of a cube is L3. The volume of a sphere is 4/3 π r3 . If L=2r, Vcube=8r3. Comparing the volume of the cube with a side 2r and a sphere with a diameter of 2r where the r's are equal gives us: Vcube/Vsphere= (8r3)/(4/3 π r3 ) or (8x3)/(πx4) As π roughly equals 3 the equation simplifies to: Vcube/Vsphere=2 or a cube with its side equal to the diameter of a sphere has a volume approximately twice that of the sphere.
Do the math.
