Hello,

For all of them, it's difficult, since its a sphere around the given color with the radius x.
For the simple cube: 9+8+9 = 26
But there is the Delta E is for those who are in the diagonal corners and edges:
DeltaE = SQR(2) * x
Or you substitute the x in those equations with more than one x with
1/SQR(2) * x
L-x a-x b-x
L-x a b-x
L-x a+x b-x
L-x a-x b
L-x a b
L-x a+x b
L-x a-x b+x
L-x a b+-x
L-x a+x b+x
L a-x b-x
L a b-x
L a+x b-x
L a-x b
L a+x b
L a-x b+x
L a b+x
L a+x b+x
L+x a-x b-x
