This is the noun area with the addition of a third dimension. Hence, it is an ideograph for a cube. A cuboid, similar to the Mesopotamian gur, was used to measure volume.

Mahadevan's sign number 149 does not have unit markings. It therefore, becomes an ideograph for procedure. It is the noun method or way.

This Indus sign shares a common root with the Chinese character 由.

Comment:

In modern Chinese 由 is more often pronounced yóu, which is the conjunction because.
