The Pyramid of Khufu is the tomb of the pharaoh Khufu of the fourth dynasty of ancient Egypt, located on the Giza Plateau in Egypt, so it is also known as the Great Pyramid of Giza. It is the largest pyramid in the world and one of the Seven Wonders of the Ancient World. As the Egyptian proverb goes: "Everything in the world is afraid of time, and time is afraid of the pyramids." ”
The construction of the pyramids was concentrated between the Third and Sixth Dynasties of ancient Egypt, that is, the period of Egypt's ancient dynasties, and the image of Egypt in the eyes of the public mainly originated from this period. The early pyramids were closer to the flat pyramid temples of the Sumerian civilization, and later evolved into the towering structures seen today.
The construction of the Pyramid of Khufu began during the Fourth Dynasty in the 26th century BC, when it was the first peak of ancient Egyptian civilization, which lasted about 20 years. At 146 meters high, the pyramid of Khufu is equivalent to 40-50 stories tall, and was the tallest man-made structure on earth until the Eiffel Tower was built. In addition to being high, the Pyramid of Khufu is large and heavy, its square base, up to 230 meters, is equivalent to the size of 5-6 football fields; The pyramid of Khufu is made of 2.3 million huge limestone stones, each boulder weighs an average of 2.5 tons, the largest can reach 100 tons, only the gap between the boulder and the boulder is filled with gypsum, not adhered with any adhesive, but the stones are still tightly sealed, the pyramid is also stable as a rock, it is estimated that the entire pyramid weighs 6 million tons, so far it is still the heaviest building in the world, the second and third heavy buildings are only 4 million tons and 2 million tons.
The construction of the Pyramid of Khufu remains a mystery to this day, and according to archaeologists, it is certain that the number of workers (mainly peasants in the spare time) who built the Pyramid of Khufu was tens of thousands. In addition to requiring a large number of labor and materials, the construction of pyramids is inseparable from a certain level of engineering and a high degree of organizational management ability. Through actual measurement, it can be confirmed that the ancient Egyptians at that time were able to skillfully use the Pythagorean theorem, the principle of leverage, friction resistance, slope principle, and calculate pi. According to archaeological findings, papyrus in ancient Egypt was first used to record the payment and use of personnel salaries and material quantities during the construction of pyramids for control. And the man who made the record was called Mele, the person in charge of pyramid stone materials designated by Pharaoh Khufu.
