Back then maths was everything? If it is so easy to build such structures why didn’t they build more? (Or just other buildings with actual conceivable purposes other than a giant tomb for the emperor of “math people”)?
Again, basic math and surveying techniques (and Stone Age tools) gets you
....the
tallest man-made structure in the world for over 3,800 years,
[6]unsurpassed until the 160-metre-tall (520 ft) spire of
Lincoln Cathedral was completed c. 1300. The accuracy of the pyramid's workmanship is such that the four sides of the base have an average error of only 58 millimetres in length.
[7] The base is horizontal and flat to within ±15 mm (0.6 in).
[8] The sides of the square base are closely aligned to the four cardinal compass points (within four
minutes of arc)
[9] based on
true north, not
magnetic north,
[10] and the finished base was squared to a mean corner error of only 12
seconds of arc.
[11]
Instead of just building the great “tomb” (and a bunch of much crappier, imitation pyramids built later) maybe they should have spent more time researching non-ridiculous tech. Perhaps a couple of these would of come in handy when the sea peoples ruined their shit a thousand or so years later...
