What comes after length, area and volume? [duplicate]

The length of the unit is 1.
The area of the unit square is 1.
The volume of the unit cube is 1.
The $\color{red}{???}$ of the unit tesseract is 1.
The $\color{blue}{???}$ of the unit 5-cube is 1.

So this is a fill in the blanks-question, but I've been wondering if there's a common term for this? I'd imagine it'd be "n-volume", but I cannot seem to find any uses of that term, so I'm guessing there is another term?

Solution 1:

The term "hypervolume" is in use, but that doesn't tell you the dimension. I don't see any trouble using "$4$-volume" to describe the amount of space the unit tesseract occupies.
