1, the side length of the square at the bottom of the pyramid *2÷ The height of the pyramid is exactly equal to 3. 14, which is π.
2. The angle between the upward channel and the horizontal plane is 26, and the angle between the lateral surface and the horizontal plane is 52, which is exactly twice of 26.
3. Bottom perimeter * tower height = perimeter: radius.
4. The weight of the pyramid × 10× 10 15 power = the weight of the earth.
5. The height of the pyramid × 10× 10 to the ninth power ≈ 65438+500 million kilometers = the distance from the earth to the sun.
6. The square of the height of the pyramid tower = the area of the triangle on the side of the pyramid.
7. The length of pyramid of khufu base is 230.36m, which is 36 1.3 1 kubit (Egyptian unit of measurement), which is about 1 year.
Extended data:
The construction of pyramids is a series of complex and arduous projects. It is estimated that pyramid of khufu used 2.6 million stones.
If nearly 10,000 masons can push ten huge stones weighing ten tons every day, it will take nearly 700 years, but in fact a pyramid can be built in about 20 years. In the era when there were no lifting tools, the reasons why workers moved and piled stones quickly were not verified.
The stones on the outer wall of the pyramid stick together closely, as if they had been cut by laser, and even a business card could not be inserted; Even with the most advanced modern civil technology, it is difficult to complete.
The stones used to build the pyramids are all transported by wooden rollers, but palm trees grow the most in the Nile valley, which is not only an indispensable food for Egyptians, but also the only shading material in the hot desert.
There is no adhesive between the stones of the tower. After at least 4500 years of wind and rain, the gap is still quite tight, and it is difficult to insert a sharp knife.
When artists carve and draw murals in catacombs and tunnels in pyramid of khufu, they don't use torches or oil lamps at all, and they probably use some special storage battery or other electric appliances that can emit light.
How the ancient Egyptians built the pyramids more than 5000 years ago has not been solved.
