Single containing bounding box instead of multiple ones

Bounding box is creating multiple boxes for each surface instead of one for the entire solid

it seems that brep join is not the answer for presenting the icosahedron as a single entity to be bounded by a single box, how can I create only a single bounding box around the icosahedron instead of multiple one for each surface?

You’ll need to flatten one of the outputs before Brep Join.

Your surfaces are in separate branches. Fix that first, then right-click BBox and check ‘Union Box’.

P.S. Or this. Note that it’s best to not pass geometry through text panels.
