For many figures, there are known formulae - you can use one of those. Otherwise, if it has flat faces, you can calculate the area of each of its faces, and add them all up.
Otherwise, if it is curved (e.g., a sphere), you can divide the surface up into lots of small pieces, of which each will be approximately flat, and add them up. This is (basically) the process called "integration".

To find the surface area of a three dimensional figure what do you have to find?
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
The sum of the areas of the face or surfaces of a three dimensional figure?
The answer is surface area.
Is it true that to find the surface area of a three dimensional figure you must find the area of each of its faces and then add them together?
TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
How do you find the surface area of a space figure?
The surface area of a space figure is the total area of all the faces of the figure
Is it true that to find the surface area of a three dimensional figure you must find the area of each of its faces and then multiply them together?
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
What is the sum of the areas of all of the faces of a three dimensional figure?
Its total surface area.
What is the answer to To find the surface area of a three-dimensional figure you must find the area of each?
... face and add them together.
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
How do you determine the volume of surface area of three dimensional space figure?
First, find the area of each 2-D face of the figure, then add those up.
Is surface area the same as area?
The term area is generally reserved for a two-dimensional polygon, but surface area is the term of the area of the different surfaces on a three-dimensional figure---the faces on the object. So no, they are not the same.
What is the formula for surface area and volume?
That depends on the figure whose surface area and volume you're finding. You could try a Google search for "volume of [figure name]" or "surface area of [figure name]".
