Is this a trick question? Seems not possible to have an odd number of unpainted faces. Cheers.

Sorry 363 refers to the cubes and not the faces. So it means (a-2)*(b-2)*(c-2)=363.
363=3*11*11,so a, b & c have to be 5, 13 & 13. Therefore the volume is 5*13*13=845.

Just the reverse of your previous question.
