how many people did it take to build
Between 10,000 and 100,000 depending on the source. The ancient Greek historian and traveller Herodotus (c.450BC) was told it took 100,000 slaves 20 years to build the Great P â¦ yramid. Modern sources put the number at 10,000. Smaller pyramids built earlier and later must have took less time and fewer people to build.
