Number the corners of a cube from 1 to 8, so that the sum of the four corners of every face is the same.

If you are looking straight at the cube label the front  corners a,b,c,d beginning top left and going counterclockwise.  Label the back corners e,f,g,h in the same method.

the corners numbered as follows:

a=8, b=3, c=2, d=5, e=1, f=6, g=7, h=4
