Why do pyramids have their shape
But the process of building pyramids, while complicated, was not as colossal an undertaking as many of us believe, Redford says. Estimates suggest that between 20, and 30, laborers were needed to build the Great Pyramid at Giza in less than 23 years. By comparison, Notre Dame Cathedral in Paris took almost two hundred years to complete. According to Redford, pharaohs traditionally began building their pyramids as soon as they took the throne. The pharaoh would first establish an "engineering department" composed of an overseer of all the king's construction work, a chief engineer, and an architect, as well as, in effect, a "department of manpower.
The two deciding factors when choosing a building site were its orientation to the western horizon where the sun set and the proximity to Memphis, the central city of ancient Egypt. The cores of the pyramids were often composed of local limestone, says Redford. Finer quality limestone composed the outer layer of the pyramids, giving them a white sheen that could be seen from miles away.
The capstone was usually made of granite, basalt, or another very hard stone and could be plated with gold, silver, or electrum an alloy of gold and silver and would also be highly reflective in the bright sun. The image most people have of slaves being forced to build the pyramids against their will is incorrect, Redford says.
According to Redford, ancient Egyptian quarrying methods—the processes for cutting and removing stone—are still being studied. Scholars have found evidence that copper chisels were used for quarrying sandstone and limestone, for example, but harder stones such as granite and diorite would have required stronger materials.

Is there any special meaning behind the pyramid shape? How were they built without earth-moving or heavy-lift machinery? In this article, we'll examine pyramids around the world, how they were constructed and who used them. A pyramid is a geometrical solid with a square base and four equilateral triangular sides, the most structurally stable shape for projects involving large amounts of stone or masonry.
Pyramids of various types, sizes and complexities were built in many parts of the ancient world like Central America, Greece, China and Egypt. In the history of Egypt and China, they were primarily tombs and monuments to kings and leaders. The pyramids of the Mayans and Aztecs of Central America were mainly religious temples, though some of them housed burial chambers. The Central American pyramids were smaller and sometimes wider than their Egyptian counterparts. What country has the most pyramids?

Another theory is that a pyramid was the easiest shape to build or that it simply represents a burial mound. Egyptian pyramids have long been a source of mystery and, in fact, the Pyramid of Giza is one of the Seven Wonders of the Ancient World. While no clue was left behind as to the reason for the triangle shape, archaeologists are able to make some educated guesses.
