The Great Pyramid of Giza
Khufu's pyramid, known as the great pyramid of Giza, is the oldest and largest, rising at 481 feet (146 meters). Archeologists say it was the tallest structure in the world for about 3, 800 years.
The Great Pyramid of Giza is a defining symbol of Egypt and the last of the ancient Seven Wonders of the World. The Seven Wonders are the seven most remarkable structures of ancient times. This is located on the Giza plateau near the modern city of Cairo and was built over a twenty-year period during the reign of the king Khufu.
This pyramid is the only one to have been built with concave sides. This means that all four side curve in slightly.

The making of pyramids
The fourth-dynasty king, Sneferu, was the first to create the pyramid shape He built three pyramids in all, but the first two were failures. Tombs were constructed of mud fashioned into modest mounds known as mastabas. This is were the idea of pyramids came from/were based on.
I thought this was cool. The ancient Egyptians who built the pyramids may have been able to move massive stone blocks across the desert by wetting the sand in front of a contraption built to pull the heavy objects. When the researchers dragged the sleds over dry sand, they noticed clumps would build up in front of the contraptions, requiring more force to pull them across. While adding water to the sand, however, increased its stiffness, and the sleds were able to glide more easily across the surface. "This is because droplets of water create bridges between the grains of sand, which helps them stick together, the scientists said. If you use dry sand, it won't work as well, but if the sand is too wet, it won't work either." Supposedly, there is around 2,300,000 stone blocks that weigh from 2-30 tons each, there are even some blocks that weigh 50 tons. It is estimated that 5.5 million tonnes of limestone, 8,000 tonnes of granite, and 500,000 tonnes of mortar were used in the construction of the Great Pyramid. Egyptians were employed and archeologists estimate the workers would have had to set a 2.5 to 15 ton block every two and a half minutes to finish Khufu’s pyramid in about 30 years.
The Great Pyramid was originally covered in casting stones made of limestones. These reflected the suns light and made the pyramids shine. It has been calculated that the original pyramid with its casing stones would act like gigantic mirrors and reflect light so powerful that it would be visible from the moon as a shining star on earth.
