In one of the oldest Indian temples, Mahabalipuram, there is a basalt pillar about 1.5m high (original height - 4m). Unlike other artifacts, the pillar was lucky to be surveyed and measured by researchers.
Let's start with the fact that the pillar with 16 faces is made of basalt (6-7 points on the Mohs scale). On the left - the calculations on the model needed in order to withstand perfectly even edges. On the right - the results of measurements, exactly 157.5 °, as in the calculations.
Historians would try to make a calculation at least once and cut out such a pillar without a single error even by 0.5 °, using a hammer and a chisel. Although, why, if they pay for voicing already accepted versions?
