The Toltec people at Cholula de Rivadabia (in central Mexico) built what is believed to be the biggest monument ever! Built between 900 and 1200 A.D., it is known as the Pyramid of Quetzalcoatl (or Feathered Serpent).
It's height is 210 feet high, with an estimated volume of 4.3 million cubic yards.
In contrast, Egypt's Great Pyramid of Cheops is twice its height, though with a volume of only 3.3 million cubic yards. Cheiops' base covers an area of 13 acres, "claimed" to be about one-third the area of Quetzalcoatl's base.
Your Task: Given this information and assuming both bases are square, determine the dimensions (and area) of the square base of the Pyramid of Quetzalcoatl. Is the last claim correct?
