Spatial dimensions describe where an object is in space, or the size & shape of an object. For example, I am six foot two inches tall. That is a
height, and is a spatial dimension. I am 300 kilometers north of Calgary, Alberta, that is another spatial dimension.
For objects, we typically measure their spatial dimensions in height, width, length. For distances, we can do a similar thing with vectors. For
example, to get from my computer to the shower in my house, I need to go up about 12 feet (I am in the basement) and north about 20 feet.
There are three common ways I have seen to describe spatial dimensions. Cartesian Coordinates (height, width, length), Cylindrical coordinates
(height, radius, angle) and Spherical Coordinates (radius, angle, other angle) Wikipedia or Hyperphysics probably describe those better than I can;
alternately, find a math text in the library and look those up, they would probably be in most calculus books.
