    I'd say 6 personally, but I don't know how to calculate that to be honest.

    d = sqrt(s^2 + s^2 + s^2) d = sqrt(6^2 + 6^2 + 6^2) d = ???

    this is an extension of the pythagorean theorem from the 2D version to the 3D version

    if you don't have a calculator, then you can use google as one http://www.google.com/search?hl=&q=sqrt%286^2+%2B+6^2+%2B+6^2%29+&sourceid=navclient-ff&rlz=1B3GGLL_enUS420US420&ie=UTF-8

    First consider calculating the Diagonal of the plane on the top of the squared.

    @viniterranova that value would just be 6sqrt2 which is rounded to 6, that's what I based my answer off of.

    After found the diagonal of the top´s cube, then use it to calculate the bottom´s diagonal cube.

    ahh clever, you use pythagorean theorem again to get the third angle, cool!
