Another good example is that Most people thing the pyramids have 4 sides, when they actually have 8
Well, unless you’re including the mirror-image identical inverted pyramid that’s underneath the one in this Google Earth view*, I can only count four sides, a very slight, possible deviation in a perfectly straight line along each side of the base does not make it eight sided.
It’s very subtle, but if you look carefully on that google earth picture you can just make out slight lines down the centre of at least 2 sides where the blocks change direction.
Such fine detail make the feat of building it even more impressive IMO.
