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]
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.
4D ounces
To freedom
is the only chance I have
4D also has duration
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.
