There is really only one other surviving ziggurat that has withstood the ravishes of time. it was built ... well read here:

... It was built about 1250 BC by the king Untash-Napirisha, mainly to honor the great god Inshushinak. Its original name was Dur Untash, which means 'town of Untash', but it is unlikely that many people, besides priests and servants, ever lived there. The complex is protected by three concentric walls which define the main areas of the 'town'. The inner area is wholly taken up with a great ziggurat dedicated to the main god, which was built over an earlier square temple with storage rooms also built by Untash-Napirisha.[8] The middle area holds eleven temples for lesser gods. It is believed that twenty-two temples were originally planned, but the king died before they could be finished, and his successors discontinued the building work. In the outer area are royal palaces, a funerary palace containing five subterranean royal tombs. ...

and what do you suppose the size of this ziggurat was ? Well before reading this try to guess ...Here are the measurements ...

... The ziggurat originally measured 105.2 m on each side and about 53 m in height, in five levels, and was crowned with a temple. Mud brick was the basic material of the whole ensemble. The ziggurat was given a facing of baked bricks, a number of which have cuneiform characters giving the names of deities in the Elamite and Akkadian languages. Though the ziggurat now stands only 24.75 m high, less than half its estimated original height, its state of preservation is unsurpassed.

Now there are a zillion possible sizes and the inch is very small just take a look at your thumb and note the width of it. That is an inch so what do you think the odds would be of The Sumerian ziggurat matching a measurement at Giza ? Pretty slim huh ? Well believe it or not if we take the measurement which they have given us of 105.2 meters we get 4141.73 inches and this equals the square root of 2 - 1 * 10,000 or 4142.14 within 1/2 an inch. If we allow a bit of an error in the measurement (and I have no idea who measured it or how accurate it is) and called it 105.5 we would get PRECISELY the measurement of The Pyramid of Menkarre of 4153.54 inches. So although the ziggurats have been said to be temples and dedicated to the gods, I am starting to think, that like the pyramids of Giza and the others in and from The Old Kingdom, they were also used as measuring tools and bench marks and maybe who knows even astronomical markers.

I should think the if there was any mathematical logic to the ziggurats it would be logical that the angle meant was 45 degrees or producing the sq rt of 2. So suggesting 105.5 by 52.75 is not out of line. However I should think that the height was probably 100 "cubits" be they Nippur of Egyptian cubits and thus when divided by 5 would yield 5 rises of 20 "cubits". this would yield either 20.42 x 100 or 2042 inches or 20.62 or 2062 inches or 51.87 meters or 52.375 meters . If we use 105.2 as a base and 51.87 as a height we get and angle of 44.6 degrees and if we use 52.375 we get an angle of 44.88,

So we are left in a no man's land because we are unsure of the true distance of the base. Is it 4141.73 inches or the match for G3 of 4153. 54 inches
