It depends on the figure.
There are simple formulae for cuboids (including cubes) and ellipsoids (including spheres). Those for other regular polyhedra and some other shapes are not too complicated, but there are also shapes where there is no option but to calculate the area of each face and sum the individual areas. And, if the shape is completely irregular, even that may not be an option.

How does knowing the area of two-dimensional figures help you find the surface area of a three-dimensional shape?
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
Find the surface area of a sphere with a radius of four?
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*42 => 201.0619298 Surface area of the sphere = 201 square units correct to three significant figures.
How do you find the surface area of a triangular surface?
to find the surface area you have to first find the area of each part then add the areas together.
How do you find the surface area of a rectagle?
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
How do you find the surface area of an oblique prism?
You will need to find the surface area of each face and add them together.
