Hi Vamsee,

   Chimera can report the volume enclosed in any surface using menu entry

	Tools / Volume Data / Measure Volume and Area

The hard part is getting a surface for your situation.  I don't know how 
you plan on defining the part that is just nucleic acid and water.  For 
icosahedral viruses you could fit an icosahedral/spherical inside the 
density map creating it with the Icosahedron Surface dialog (Tools / 
Higher-Order Structure) and moving it to the right place using the Model 
Panel "active" buttons.
