Answer it

Pyramids are a triangular shaped rock structure which were built by early Egyptian settlements.
Pyramids were built during the early (2630 BC) and middle period of the kingdom. Later tombs (16th to 11th century BC) were cut into the limestone of the Valley of the Kings.
Not especially. The only thing truly remarkable about the pyramids is their size; the rest of it is pretty basic mathematics... and as the demotivational poster says, "You can do anything you set your mind to when you have vision, determination, and an endless supply of expendable labor."
The great wall of China, can be used as an example of early evidence of management principles at work. How it was built shows the division of labor, increased productivity by increasing each worker's skill and dexterity. The pyramids of Egypt can be an example too.
Upper Egypt and Lower Egypt
The types of pyramids built in Egypt evolved primarily due to advancements in architectural techniques, changes in religious beliefs, and shifts in political power. Early pyramids, like the Step Pyramid of Djoser, showcased a progression from mastabas to more complex structures, reflecting a desire for grander burial sites. Over time, the construction of smooth-sided pyramids, such as those at Giza, represented both an architectural innovation and a reflection of the pharaoh's divine status. Additionally, as resources and labor dynamics changed, so did the design and scale of these monumental tombs.
That is not known, though some of the pyramids were built around that time. What is known is that Joseph planned and oversaw the building of grain-storage facilities throughout Egypt (Genesis ch.41). Some attribute to Joseph the construction of the ancient Egyptian irrigation canal which bears his name, called the Bahr Yussef.See also:More about Joseph
