Taking a cubit as 18 inches and a handbreadth (4 inches) for the vessel's thickness (according to 2 Chronicles 4:5), we obtain an inner diameter of 172 inches (10 cubits minus 2 handbreadths for the two rims) and a correct value for pi: about 3.14. <ref> Lindsell, '''The Battle for the Bible''', Zondervan, 1976, pp. 165, 166</ref> |

The easiest places to measure the diameter would be across the wider rim, and the easiest place to measure the circumference would be around the body below the rim.<ref>{{cite web | | * That both the diameter and the circumference are measuring the same part of the object.
