Is there any evidence for the Golghar being constructed to preserve grain for military forces specifically, as opposed for the whole population? The citation just points to a tourist guide site, which is hardly an authoritative source. The Government of Bihar's Directorate of Archaeology page about the Golghar makes no mention of it being dedicated to military use. If the capacity of the granary was 140,000 tons then surely that would far exceed what would be necessary to feed a large garrison? James Harvard (talk) 14:50, 21 June 2008 (UTC)[reply]

I suspect there is a problem with the cited weight capacity of Golghar...

Simplifing (greatly) Golghar can be considered to be half a sphere of radius 29m (its height).

Volume of a sphere = (4/3) * PI * r^3.

Therefore the volume of Golghar:

= ((4/3) * PI * 29^3) / 2
= ((4/3) * PI * 24389) / 2
= 102160 / 2
= 51080m3
= approx 50000m3

If Golghar holds 140000 tons of grain then each ton occupies:

= 50000 / 140000
= 0.357m3

Now, if one metric tonne is the weight of a cubic metre of water, this suggests that the tons of grain in Golghar are something like three times heavier than water, which is unlikely.

My volume calculation clearly errs on the high side, so the actual internal volume of Golghar must be much less. If this is the case then each of the 140000 tons of grain will have even less space, which therefore leaves this mythical grain as being even denser than my initial calculation suggests.

A number of things need to be done:

• confirm my primitive calculations for the internal volume of Golghar.
• arrive at a mathematically reasonable number of tons for the capacity of Golghar, given an approximate density of grain.
• if my suspicions prove correct the original source (if it can be found) for the weight capacity of Golghar as being 140000 tons should be identified as being incorrect.
• the derivation of the correct approximate weight capacity of Golghar should be explained and the result cited.
