Question 283829
I don't really know.


But, .....


I did a search on the internet and found an article that indicated that the surface area of the pyramids was originally limestone.


Maybe they needed to determine how much limestone they needed?


Maybe somebody today wanted to know how much limestone they needed?


Here's the article.
