Well, you asked for WED, so I will slighty make a notice that you can query these infos also during runtime.. so, here is how you get it in WED:

Select an entity and open its properties panel. Then go to the "object" tab. There you'll have several numbers..

Position, Rotation and Scale reflect the numeric values of these properties from left to right: x,y,z

Bound values are also to be read from left to right as columns: x,y,z direction and the upper row means the extend in positive direction and the lower one into negative direction.
