The Great Pyramids Of Giza

The Great Pyramids of Giza the great pyramids of Giza are some of the most famouse manmade objects in the world. they have been famous since ancient times. infact, the great pyramid of khufu is one of the most wonder of the ancient world that still surivves. it 's base cover over 13 acres, and its volume is around 90,000,000 cubic feet. these massive stone structures were duilt around 4500 years ago. there are 2-3 million blocks of lime stone, which wight from 2.5 to 15 tons each. So, what I think at that time built a pyramid like that huge size had a markable affect in the ancient egyptian life. they had a different society, different resources of economy and different

It had features of a planned economy. As money was not invented, barter system prevailed in buying and selling commodities. Cost was measured in a Deben, a copper weight of .5 ounces. Ancient Egypt was basically what is called a "supply state." Products for consumption were delivered to state or temple institutions, which in turn distributed food and other goods to the population.Jobs in Ancient Egypt included government officials, soldiers, scribes, doctors, merchants, dancers, fishermen, hunters, bakers, carpenters, coffin-makers, spinners, weavers, jewellers, pyramid builders, Egyptian artists, and farmers. Most Egyptians were farmers. The river Nile encouraged agriculture by providing a source of irrigation and also fertile black soil. Agriculture created most of Egypt 's wealth. Grain, vegetables, fruit, cattle, goats, pigs and fowl were grown, and fish from the Nile were caught, and eventual surpluses, after deduction of the various taxes, were sold on the markets. The main crops grown in Egypt were wheat, barley, lettuce, beans, onions, figs, dates, grapes, melons, and cucumbers. The pharaoh was the controller of the

. The accuracy of the pyramid 's workmanship is such that the four sides of the base have an average error of only 58 millimetres in length. The base is horizontal and flat to within ±15 mm (0.6 in).The sides of the square base are closely aligned to the four cardinal compass points based on true north, not magentic nortgh and the finished base was squared to a mean corner error of only 12 seconds of arc. The completed design dimensions, as suggested by Petrie 's survey and subsequent studies, are estimated to have originally been 280 royal cubits high by 440 cubits long at each of the four sides of its base. The ratio of the perimeter to height of 1760/280 royal cubits equates to 2π to an accuracy of better than 0.05% (corresponding to the well-known approximation of π as 22/7). Some Egyptologists consider this to have been the result of deliberate design
