The Great Pyramid of Giza is a well known ancient building that is located on the outskirts of Cairo. It contains complex internal architecture which has been analysed in the previous papers in this series, and in particular in paper B ''The vertical chamber stack of the Great Pyramid ­ part 1" it was proven that the upper and lower chambers of the building are stacked above each other in a logical manner which allows the vertical location of the chambers to be deduced without the need for surveying. The vertical architectural stack that was established in that paper terminated at the ceiling of the first of the roof chambers above the pyramid's upper chamber and at a specific half-integer altitude above the base of the building when measured in the architect's unit of measurement, the cubit.

In the three subsequent papers, additional information regarding the horizontal stacking, the position of the roof chambers, and the binary data contained on the upper chamber walls was discovered and documented.

In this paper I extend the vertical stack of the architecture from the ceiling of the first roof chamber up to the mid height of the pyramid using the system that is inherent in the architecture. The information that was discovered in the previous three papers is used to continue the vertical stack in a logical manner until the point that the half height of the pyramid can be determined from a continuous series of data from the base level of the pyramid upwards.

I show that the data that is inherent in the upper portion of the pyramid's vertical stack design incorporates fundamental geodesic constants from which I deduce that the Great Pyramid must be a geometric scale model of Earth.
