Title Description
Three Dimensions The Dimensions of space or volume are Three Dimensions, typically labeled with rectangular, spherical, or cylindrical coordinates.
Total Total means two things in mathematics.
It is the result of addition, as a sum; we add terms or addends to achieve a sum, or total.

The relation need not be equality.
So if A < B and B is < C, then A < C.
