multiple surfaces 3d sketch

Let me first say, that even though I've been using Solidworks for 8 years (has it been that long) I don't have much experience with surfacing.

See picture - how do I make 6 surfaces from this 3d sketch? I'm not looking for work arounds that only work for a cube, because ultimately I want to do a more complex shape.

I drew a 3d sketch of a cube.... can you make multiple surfaces for each face of the cube? For that matter, how to make the first surface?

I thought I could use a filled surface, but it grabs the whole 3d sketch instead of just the edges. A filled surface works on a 2d sketch, but not a 3d?
