PERSPECTIVE
They can be measured by their linear measures in three orthogonal directions.
Often these are three linear dimensions. Normally these are the dimensions in mutually perpendicular directions, but they need not be: they can be in any three directions which are not coplanar. Depending on the context, the linear dimensions are called:Length;Breadth or width; andHeight or depth.Also, the answer may comprise measure one distance and two angles: as might be done to locate an object in astronomy.
A cubic foot that is three inches thick covers an area of 4 square feet. This is an area, with dimensions [L2]. A linear foot is a measure of distance, with dimensions [L]. There is no sensible way to convert one to the other.

Linear perspective is a mathematical system for projecting the three-dimensional world onto a two-dimensional surface, such as paper or canvas

PERSPECTIVE
By adding all three sides (length, breadth and height) all-together we get the linear dimensions of a box.

Artists use a form of art called perspective. An objective farther away would appear smaller due to the great distance. On the paper, it is no further away, but it can be drawn to look like it is, giving the impression of three dimensions.
