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!

You'd just continue saying 'volume', alternatively 'k-dimensional volume' or 'volume of the n-dimensional object'. Like for spheres: https://en.m.wikipedia.org/wiki/Volume_of_an_n-ball

The n-dimensional volume of a Euclidean ball of radius R in n-dimensional Euclidean space is:[1]

  • {\displaystyle V\_{n}(R)={\frac {\pi ^{n/2}}{\Gamma {\bigl (}{\tfrac {n}{2}}+1{\bigr )}}}R^{n},}

I'm going to start calling area "2-dimensional volume"

[-] mumblerfish@lemmy.world 19 points 2 months ago

Only if you also call length "1-dimensional volume".

[-] Notyou@sopuli.xyz 11 points 2 months ago

What happens if I turn the dimensional volume up to 11?

[-] ironhydroxide@sh.itjust.works 7 points 2 months ago

Well if it's in 1-dimensional space, then you have a line the length of 11 units.

[-] luciferofastora@lemmy.zip 5 points 2 months ago

Well, you could just make 10 higher and make that the highest

[-] threelonmusketeers@sh.itjust.works 1 points 2 months ago

"But- but this one goes to 11."

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!

Also try the math comms this is more of a math question and also I really really wanna know the answer.

is the only chance I have

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.
