The ancient Greek scholar Herodotus who lived around 450BC when the Great Pyramid was already 2000 years old, was told that it took 100,000 slaves twenty years to build.
Most modern historians accept the twenty years but believe it was more like 20,000 or 30,000 . It is thought there were about 5,000 skilled workers and administrators. The rest were labourers whether they were slaves or not is for you to decide.

Khufu ruled for many years. He ruled from 2590- 2568 BC. Many people believe he was cruel because he treated his workers badly and only gave them onions to eat. he built The Great Pyramid at Giza during the yearly Nile's flood so that the farmers would only work on his pyramid
Pharaoh Khufu had 20,000 slaves to make his Great Pyramid.
There are many different theories about the purpose of the Great Pyramid. Along with not being able to conclude absolutely who built the Great Pyramid, mankind also does not understand why it was built. Many believe that Pharaoh Cheops (or Khufu) built the Great Pyramid for his tomb around 3350 BC, because many of the other pyramids in the area have been found to be burial chambers for the various kings of Egypt. Now, there are some that believe the Great Pyramid monument was a time capsule left by an advanced civilization. There may have been some leaders of this civilization wanted to leave a message to future civilizations. Others think it was some civil service project.
It is not really known for definite who build the sphinx, but one of the current ideas is that Khufu's son Djedefre built the sphinx in the image of his father after his death. Although, there are still many disagreements, some think khufu (builder of the Great Pyramid) built the sphinx, while others believe it was built by his other son khafre (the builder of the middle pyramid).
