That would be different for every shape! Start with the formula for point charges and integrate over all the infinitesimal charges in the shape. Spheres work out nicely; other shapes do not.

For spheres, just use the point charge formulas - as if the entire charge was located at the center point. Make a note that you need to work that out for yourself once you take 3D calculus.
