How long did the pyramid take to be build?

Around twenty years

Explanation:

In my old history book, it says "Herodotus was told by his Egyptian guides that it took 20 for a force of 100,000 oppressed slaves to build the pyramid (with another 10 years to build a stone causeway that connected it to a temple in the valley below)."

So, for the average pyramid it would take 20 years (give or take depending on things like weather, the slaves building it, etc)

the answer is a. mothma gupta.

answer; the above statement is (false);
