DB: "However from the any of sides of The Great Pyramid to the base of the wall (although I have heard that it is not equal all the way around, is it ?)"
The distances to the inner enclosure walls and outer enclosure walls from the sides of the pyramid are not equal all the way round.
Inner enclosure: N and E walls, 10.2m, W and S walls less than 10m.
Outer enclosure: N and W walls, 23.6m (45 cubits); S wall 18.75m (the wall is not exactly parallel with the S side of the pyramid)
