Wow, that's quite informative. Thanks Unfan
So heaven is described as a shining city with streets paved with gold, all kinds of gems in the foundations and parts made out of glass. It's as width is the same as it's length and it's height so it sounds almost like it's cube-shaped.
The lengths are 12 000 furlongs and a furlong is supposedly about 200 meters. Then it would be ..
12000 * 200 = 2400000m / 1000 = 2400 kilometers in all directions.
Pretty impressive! 3 gates on each side doesn't sound so much when you take the scale into consideration.
