An overview of the pyramid construction in the ancient egypt
Estimates given by various archaeologists for the size of the workforce at Giza tend to hover around 10, people for all three pyramids. However, the basic limestone was extracted directly from the site or nearby.

Inside egyptian pyramids

The first historical accounts of the construction of these monuments came centuries after the era of pyramid construction, by Herodotus in the 5th century BC and Diodorus Siculus in the 1st century BC. It was made out of stones weighing an average of 2. This silting could also have been done artificially, by moving the sand on the side of the pyramid. Solid walls of stone ran from the center, and shorter cross walls formed a series of chambers filled with stone blocks, ruble or mud bricks. For instance, mathematician Kurt Mendelssohn calculated that the workforce may have been 50, men at most, while Ludwig Borchardt and Louis Croon placed the number at 36, Many scholars believe that the Sphinx monument, which lies near Khafre's pyramid, was built by Khafre, and that the face of the Sphinx was modeled after him. Many of the pyramids still survive today for us to see and explore. It may be that there was a new lever on each tier of steps, or perhaps there was only one lever, quite portable, which they carried up to each tier in turn; I leave this uncertain, as both possibilities were mentioned. To add to the uncertainty, there is considerable evidence demonstrating that non-standardized or ad hoc construction methods were used in pyramid construction Arnold 98,  Lehner Houdin and Brier and the Dassault team are already credited with proving for the first time that cracks in beams appeared during construction, were examined and tested at the time and declared relatively harmless. With their 'rudimentary tools,' the pyramid builders of ancient Egypt were about as accurate as we are today with 20th-century technology. They were built mostly of limestone. The first, and probably the only step pyramid ever completed, is that of King Netjerykhet Djoser at Saqqara.
The internal construction of most true pyramids consists of a series of buttress walls surrounding a central core. The pyramids of the VIth Dynasty were rather in raw bricks covered with fine limestone blocks of the quarries of Tourah.
How the ancient Egyptians did this is not fully clear. Assuming that the step pyramid was built before the outer structure, and then the packing blocks were laid on top, the ramps could have run from one step to another rather than approaching the pyramid face at right angles.
Occasionally, granite was used in the outer casing as well, such as in the Pyramid of Menkaure. Except for the few partly decorated corridors in the Step Pyramid of Djoser, earlier pyramid interiors had, on the whole, been left blank, including those at Giza.
Since the discussion of construction techniques to lift the blocks attempts to resolve a gap in the archaeological and historical record with a plausible functional explanation, the following examples by Isler, Keable, and Hussey-Pailos  list experimentally tested methods.
An outer casing was usually added, and although quite effective in the short term, it did not even come close to the earlier construction methods. Houdin's thesis remains unproven and inUCL Egyptologist David Jeffreys described the internal spiral hypothesis as "far-fetched and horribly complicated", while Oxford University's John Bainesdeclared he was "suspicious of any theory that seeks to explain only how the Great Pyramid was built".
Packing blocks are stacked until the dimensions were right, and then finishing blocks usually limestone were the last touch. If this hypothesis seems at first far-fetched, it is not only very serious but partly verified by the internal temperature records of the pyramid.
What tools were used to build the pyramids

To get an idea, a fresco of the middle empire shows us 4 rows of 43 men, a total of , to draw a statue that is estimated at 60 tons. According to one theory, the pyramid form was intended to represent the first mound of creation that the Egyptians believed rose from the waters of chaos at the beginning of time. Inscriptions and texts also allow research into Egyptian grammar and language. Later kings, of the 12th dynasty, would return to pyramid building during the so-called Middle Kingdom phase, but it was never on the same scale as the Great Pyramids. Wraparound ramp The principle of the enveloping ramp is simple, it consists of having only one ramp that rotates at right angles to each stop of the pyramid. Davidovits's method is not accepted by the academic mainstream. It was made out of stones weighing an average of 2.
