What is the 4D equivalent of 3D volume?

Is there a different/special term for the space a 4D object occupies in 4D space?

Thanks in advance.

Some suggestions:

* Hypervolume works in the same vein as ‘hyperplane’ etc. A lot of syllables though.
* Measure is the general term for what you are talking about, but it's very general so make sure it's clear from context which measure you mean. This is usually not a problem.
* Content is one of those great flexible middle-ground words that you can define on a paper-by-paper basis.
* Prefix by dimension, e.g. 4-volume, 4-measure, 4-content. Useful if you have to deal with many different dimensions.
