5- Seventh wonder of the world:

This pyramid is too much,
Everything is there, too tall, too big, too heavy, too precise, too perfectly executed, calculated, planned.
146 m height, 230 m base, volume 2.6 million M³ weight about 6.5 million tons.
The ratio of the height to the half base makes the famous fraction 14/11 which is the tangent of the angle that make the faces with the horizontal plane.
This value makes it that the circle which diameter is the height of the pyramid has the same perimeter than the 1/2 base.

Paraphrasing the RHIND papyrus which expressed that a 9 diameter circle as the same surface than a square of 6, a 14 diameter circle as the same perimeter than a square of 11.

Making it in royal cubits and dividing all the values by forty, the 1/2 base is 22, the eight is 7.

The 1/2 base perimeter is 22, the diameter 7 so the Egyptian π was 22/7 so to say 3 and a palm (the palm is 1/7 the cubit) missing the “modern” value for around 1/1000.

I’m not going to add to an incalculable number of speculations!

On the other hand it’s easy to find that the builders were pragmatic people look at it:

The ancien Egyptians used the SKD to mesure an angle the SKD is the cotangent of the angle. The SKD of the face with the plan is 11/14, multiplie all this by two 22/28.

28 was the smaller part of the royal cubit, called the digit and 22 is the sum of a double palm which is a subdivision ( 8 digits) of the cubit plus a great claw (14 digits) an other subdivision of the cubit.

At the end the SKD of the face with the horizontal is a double palm + a great claw to the cubit, that’s it!


The consensus estimates about 2.3 million number of blocks that constitute it.

Its casing, the skin of the pyramid, originally built with fine limestone from the quarry of Turah has almost completely disappeared except for 8 blocks at the base, its volume of about 90 000 M3 is could have been made 90 000 blocks, or 4% of the total number.

The pyramid rests on a knoll carved in the initial hill,  which is not flat, it comprises in its center a stump which was measured to 6 m height where it is visible whose base would be 170 m by 170 m. But unfortunately we will never know the real shape of this mount.

Its interior is particularly complex compared to other pyramids, it contains 3 known rooms, the underground cave, the lower chamber so-called of the queen’s, the upper chamber known as the king’s .

Each room is accessed by a corridor, descending for the underground chamber, which is 100 m long largely dug in the rock of the base, horizontal for the low chamber entirely masonry, the upper chamber communicates with the great gallery, through a passage called the room of the harrows, the great gallery is monumental  47 m long, 2 m wide, 8 m high inclined to around 26 ° ( its SKD is 2 exactly ) equipped with a magnificent corbelled ceiling.

From the descending gallery  one could have access to the great gallery by an ascending corridor of 37 m long also inclined to 26 ° if it had not been hermetically sealed by 3 blocks of granite.

The junction of these 3 corridors communicates with the bottom of the descending gallery by a narrow shaft called service well.

The lower chamber has a niche taken in the thickness of its wall, giving the east on a clear narrow corridor  long 5.5 m in a masonry, then dug long 10 m in the filling stones.

The entrance to the descending gallery is surmounted by a double chevron roof, of the same shape as the roofs of the lower and upper rooms.

Between the ceiling of the upper chamber and its roof is inserted on 13 m a stack of megaliths which weigh between 30 and 65 t each which constitute what is known as the “chambers of discharge”.

All these volumes are empty and bare, without painting, without engravings, and it is unlikely that the hollowed stone found in the upper chamber could have been the sarcophagus of a great king.

All these volumes are aligned on the same vertical plane whose axis is 7 m east of the axis of the pyramid.

The volume of the lower chamber is centered as well on the central east-west axis of the pyramid.

However there is an invisible part but present in the pyramid that supports all the volumes that I just described, it is a masonry which starts from the initial mount  and which goes up following the galleries.

This central masonry is oriented north-south it starts from the north base under the descending gallery, extends south under the ascending gallery, then under the horizontal gallery and the great gallery, then under the lower chamber, then under the upper chamber.

Its southernmost end is under the upper chamber 16 m south of the vertical axis of the pyramid.

Its east end is a masonry that extends 5.5 m outside the wall of the lower chamber, which puts it 15 m from the central axis.

(My guess: this masonry houses the cage of the first stage lift as well as the pit and cage of the second stage. Its known western end is 3 m west to the central axis.)

In all this basement as a section of 18 m wide and 130 m long culminating at 42 m height under the base of the upper chamber.

We will probably never know the exact configuration of this basement we are only sure of one thing, it exists!

It is certainly not an assembly as neat as that of the casing stones, but much more precise than that of the filling stones, because if this base moves (and it moved despite the precautions taken) the rather fragile structures which are at above can crack, which would be unfortunate and that happened in the upper room.

I have just briefly described what we have found so far in this pyramid.

Arriving at the end of this study we will have discovered many other important elements.

First, the exact location of the mortuary complex that remains to be unveiled.
All the water circuit and elevator shaft of the 3 stages visible.
The 2 stages of elevators to go to the top.
The real entrance to the pyramid and the access gallery that leads to the loading point of the lifts.
After reading this study, some archaeologists will have to work! it’s my hope.
