For example, for any number of different charges enclosed in a box or sphere, if I move far away can I consider the object as a point source having the sum of the enclosed charges?

Likewise, if I'm moving through the interior of a sphere with a constant charge per unit volume, and I'm some x distance from the center, can I conceive of the flux at this point as being the same as it would be if i was on the surface of a smaller sphere with radius x? i.e.,, would the concentric outer layers of the sphere cancel each other out.

Anyone willing to share their favorite conceptualizations with this kind of stuff is much appreciated.
