The Great Pyramid of Giza is also recognized as the Pyramid of Khufu, the Pyramid of Khufu and the Pyramid of Khufu. It is the largest and oldest structure in the world. This pyramid is the oldest of the three pyramids of the Giza necropolis. It is also the largest of all (Larry, 2000). This great pyramid is located on the northern edge of the Giza Plateau, 25 km from the outskirts, southwest of Cairo, Egypt. It is the only monument still standing of the Seven Wonders of the Ancient World (Crystalink, 2011). The pyramid is said to have been built as the tomb of the Egyptian King Khufu of the Fourth Dynasty (known in Greek as Khufu). The pyramid is believed to have been constructed over 20 years by a workforce of 100,000 oppressed Egyptian slaves (Cleveleys, 2011). ) and was completed around 2560 BC. It took another 10 years to build a stone gateway that connected it to a temple in a valley below (Krystek, 2010). The pyramid was the tallest structure ever built by man in the world for more than 3,800 years until the 19th century, and is now approximately 4,500 years old. Originally, the height of the pyramid was 146.6 meters (480.97 feet), but due to erosion, its height now measures 138.8 meters (455 feet). This is equivalent to a building consisting of 48 floors. The pyramid has 203 steps or paths to its summit (gizapyramid.com, 2011). Its base covers an area of ​​13 acres (568,500 square feet). It was built with more than 2,500,000 limestone blocks, each weighing between 2 and 70 tons. The blocks of stone were moved using huge machines. Its volume is approximately 2,500,000 cubic meters (90,000,000 cubic feet) and its total mass is approximately 5.9 million tonnes. Based on this information, it shows that for...... middle of paper...... g. All things considered, the Egyptians may have had a much broader understanding of geometry than previously thought. The dimensions of the Great Pyramid may be indicative of a very sophisticated measure of understanding on the part of its designer. Works Cited Krystek L. The Museum of UnNatural Mystery (2010).
