How was the Egyptian pyramid built?

Answer 1

Thousands of workers spent years of hard work to build the pyramids. Farmers did a lot of the work during summer when the Nile River flooded and they could not farm. Surveyors, engineers, carpenters and stonecutters helped to build the pyramids. The first engineer who built pyramids was Imhotep who also served as an official for the pharaoh. The workers searched for stone in places throughout the Nile River valley or in Upper Egypt. After locating the stone artisans used copper tools to cut the stone into huge blocks. The workers used rope to fasten the blocks onto wooden sleds that were pulled along a path made of logs to the Nile River. The stones were then moved onto barges that carried them to the building site. There, the workers unloaded the blocks and dragged or pushed them up ramps to be set in place at each new level of the pyramid. The Egyptians faced many challenges as they built the pyramids, but these challenges, however, led to important discoveries. Each pyramid rested on a square-shaped foundation, with an entrance facing to the north. To find which direction north was the Egyptians studied the skies and developed an understanding of astronomy and with this knowledge, they invented a 365-day calendar with 12 months divided into 3 seasons. This calendar then became the basis for our modern calendar. The Egyptians also made advancements on math. Egypt's pyramid builders had to calculate how much stone was needed to build a pyramid and had to measure angles in order to construct a pyramid's walls. To be able to do this, they invented a system of written numbers based on 10 and and also created fractions, using them with whole numbers to add, subtract, and divide.
