There are different formulae for calculating the surface areas of different 3D figures. If the 3D figure is a polyhedron, then each face is a ploygon and you can use the various formulae to calculate the area of each face and then add them together.
There are straightforward equations for ellipsoids, and members of the conic family but other 3D shapes have more complicated formulae.

How is the surface area different from area?
Surface area is all the areas for a 3 figure. Area is for only on side of a 3d figure
What is the sum of the area of all the faces of a 3D figure?
It is the total surface area.
What is a formula for surface area of triangle?
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
How do you find the surface area of a 3d trapezoid?
You find the surface area of each of its six faces and add them together.
Can you find an area of a 3D figure?
Yes, if it is bound by plane figures, just add the area of each plane figure. If it has a curved surface, divide it into many small pieces, to approximate the area with small rectangles or triangles, then add them up.
