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 a 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 means reason or cause.
