Yes, they do have more surface area, and they could even be seaid to contain their own resonators, since they are hollow. But, even so, it is the air that carries the vibrations which stimulatie the sympathetic vibrations, not a sounding board connected to the original stimulauus and not cables or anything. else. Sound waves can travel through air, water, wire , etc. On a sitar, the vibrations may travel from the plucked string to the sympathetic string through the air and/or the soundboard; in either case the resonator of the soundbaoard will serve as an amplifier to make the all the sounding strings louder. Now htathat I think about it, I remember quite a few years ago payinglaying a solo flute piece with the soundboard of the pieano open. PLlaying the flute near the piano strings with the dampers off caused the same effect of certain strings vibrating sympathetically. Of course, the soundboard of the piano was not connected directly to the flute! So the aire m must have been a sufficient carrier of the sound waves to stimulate the strings.
