Pyramids of Giza consist of three pyramids that are amongst the biggest in Egypt! As you guys already know, pyramid building consist of many many steps involving mathematical, astronomical, and physical labor. The three pyramids are- Pyramid of Khufu, the Pyramid of Khafre and the Pyramid of Menkaure.
Pyramid of Khufu (also called the Great Pyramid) is the largest of the three pyramids of Giza. It was built for fourth dynasty Egyptian Pharaoh Khufu. This pyramid required one hundred thousand people to work on the it, even through the Nile’s annual flood. Pyramid of Khufu’s height is 146.5 metres (480.6 feet), and it has a angle of 51º 52’. It was constructed using 2,300,000 limestone blocks, each weighing an average of 2.5 tons. Overall the process of building this pyramid took over 20 years.
Pyramid of Khafre is built for Khufu’s son, Khafre (pharaoh). The Pyramid of Khafre seems taller than Khufu’s, because it is built on higher ground, with a steeper angle. This pyramid is 447 .5 feet (136.4 m) tall, making it 33.5 feet (10.2 m) shorter than the Great Pyramid.
The third pyramid is the Pyramid of Menkaure, the smallest of the three. This pyramid was built for Khafre’s son Menkuare (fourth dynasty Egyptian Pharaoh). The height of this pyramid is 228 feet (70 m), which is less than half the height of the pyramid built by Khufu. The lower layers are made up of red granite and the upper layers are made up of white limestone.
