• The great architect of ancient Egypt, Imhotep (2,655–2,600 B.C.), who designed the Great Pyramid, is the earliest scientist who is known by name today.
  • The Great Pyramid of Cheops (Khufu) at Giza, built around 2,570 B.C., used 2,300,000 large stone blocks that weigh a total of 7 million tons.
  • In terms of volume, the largest pyramid in the world is in Mexico, not Egypt. The Cholula Pyramid was built around the year 100 from sun-dried brick and earth. Although only 177 feet high, less than 40% of the height of Egypt’s Great Pyramid of Khufu at Giza, it covers an area of 39.5 acres compared to Egypt’s 13 acres.

I couldn’t tell you the amount of times I see people make this mistake.

There is no evidence WHAT-SO-EVER that Khufu had anything to do with building the pyramids. The only evidence to support it was discredited as the guy who faked it (Colonel Weiss i think his name was) copied the hieroglyph from a book … Which had the wrong ‘spelling’ in it.

Also, where the hell did you get the idea that Imhotep designed the pyramids? This is complete speculation folks, don’t believe a word of it. 
The most likely person to have overseen the construction of the pyramids was Saurid, son of Sahluk, son of Sirbak, son of Tumidun, son of Tadrasan, son of Husal; one of the great kings of Egypt prior to the great flood. He was said to have lived in Amsus and was said to have been the builder of the two great pyramids near Misr.
