The Site of Teotihuacan, “The Pyramid of the Sun,” as it has been dubbed, demonstrates advanced math. The pyramid’s base has a perimeter of 2932.8 feet, while the pyramid has a height of about 233.5 feet. If we take the ratio of base to height, we get about 12.56, or rather, 4p. Although to some this is thought to be a coincidence, the pyramid’s actual ratio is less than 0.05 per cent off of the true value for 4p.
