[Closed] bounding box

is it possible to return the bounding box selection from an object or a selection of objects and would it be possible to return width, height, depth, pivot location?

for example if i select a bunch objects could i get the bounding box information about the bounding box that encompases all the objects inthe selection?

writing a little script that has to know the lowest point of a selection of obects to add a ground plane to amongst other things
