to find the diameter of the sphere you have to find the diagonal of the cube by using the Pythagoras theorem twice.

the first time is to find out the diagonal length of the base of the cube.

sqrt(6^2 +6^2)=sqrt(72)

with this new information we can now find out the diagonal of the cube (diameter of the sphere)

sqrt(6^2 +(sqrt(72))^2)

=sqrt(36+72)

=sqrt(108)

=6root3
