Age of pyramids carbon dating
The original height of the Pyramid was 146.5 m (488 ft), but today it is only 137 m (455 ft) high, the 9 m (33 ft) that is missing is due to the theft of the fine quality white Tura limestone covering, or casing stones, for construction in Cairo. The Mesopotamians built the earliest pyramidal structures, called ziggurats.
In ancient times, these were brightly painted in gold/bronze.
As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base).
The square pyramid, with square base and four triangular outer surfaces, is a common version.
The facings were often glazed in different colors and may have had astrological significance.
Its four sides face the four cardinal points precisely and it has an angle of 52 degrees.The Egyptian sun god Ra, considered the father of all pharaohs, was said to have created himself from a pyramid-shaped mound of earth before creating all other gods.Ancient Egyptian pyramids were in most cases placed west of the river Nile because the divine pharaoh's soul was meant to join with the sun during its descent before continuing with the sun in its eternal round.Pyramids have been built by civilizations in many parts of the world.The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla.The Great Pyramid of Giza is one of the Seven Wonders of the Ancient World.
