The 3 dimensions of space, are they an inherent property of space, or are they our invention for practical-calculative purposes?

We all agree that our space is 3-dimensional, and not, for example, 2-dimensional. But the question is, does the space truly have any dimension at all? I don't mean to say it has zero dimensions or any other number of them. But that what we call
3-dimensions, aren't they just our need & invention for calculative purposes, emerging from the 3 axes lying 90 degree to each other?

Most modern theoretical physics models rely on 10 or more dimensions, these propositions also arise out of computational convenience (the only way the math makes sense so far).
