If the three-dimensional figure is bounded by polygons, you calculate the area of each polygon, and add it all up. If the three-dimensional figure is bounded by some curve (as in a sphere), you basically need integral calculus. The basic idea is to divide the surface into small pieces, assume that each piece is approximately equal to a rectangle, triangle, or another convenient (and well-known) 2D figure, and add the surface areas up. Also, you analyze what happens when the individual pieces are made smaller and smaller. Integral calculus has some special methods to speed this task up, but that is the basic idea.
