To detect a box you should probably do a rectangle detection.

Opencv has a sample of that: http://code.opencv.org/projects/opencv/repository/changes/tags/2.4.1/opencv/samples/cpp/squares.cpp

You can read this for more information: http://stackoverflow.com/q/11015069/1085483

To calculate height and width of box, if you mean real distances instead of pixel distances, it is not a beginner topic.
