A question about TGeo volumes

Dear ROOTers,

I hope that someone can help me in a subtle question about building TGeo volumes.
My question is the following: suppose that I have to implement a box of a given material which is surrounded by another box of another material. My first idea would be to build a composite shape given by the subtraction of a box with the dimension of the "outer" one, minus the shape of the inner one, and then to insert inside it (in the remaining empty space), the inner box.
Do I gain the same result if I create the outer box as a "full" box and then I insert the inner box as a node of this one?

Thanks, best regards
