    I think you are looking for Lebesque measure, wikipage.

    Quote: “For lower dimensions n = 1, 2, or 3, it coincides with the standard measure of length, area, or volume. In general, it is also called n-dimensional volume, n-volume, hypervolume, or simply volume.”

      Wonderful answers all around, but this seems to be the succinct, specific one-word answer: it’s a Lebesgué!

    A popular example of a four-dimensional polytope is the Tesseract, which is just a 4D cube. Four dimensional and beyond polytopes have what is called a hypervolume. This can be calculated by using Lebesgue measure, which is beyond my understanding of mathematics.

    Fun fact: four-dimensional analysis is common in the development of modern parallel supercomputing!

      Only if time is your fourth dimension. OP is likely asking about a fourth spatial dimension, since that’s much more in keeping with the progession of 1D > 2D > 3D

      In specific applications where it is useful to consider time as a 4th spacial dimension.

      So if you’re not talking about relativity, it’s probably not.
