How many acres does the base of the great pyramid of khufu cover

According to crystalinks website it covers about 13.6 acres. I hope this helps. :)

13 acres

Explanation:

   The Great Pyramid of Khufu is located 15km south of Cairo, Egypt. This monstrous structure occupies 13 acres. The pyramid was originally built with blocks of polished limestone, which gave it a shiny and reflective surface (this cover was destroyed during the Arab invasions many centuries later). It is considered one of the great engineering marvels of history, and a satisfactory explanation of its construction has yet to be found.
