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.

Find the surface area?
It depends on the surface area of what!
How do you find the area of 3 numbers?
You don't. You can find the area of geometric figures, not of numbers.
How do you find the surface area of a parallelogram?
The formula to find the surface area of a parallelogram is Base*Height.
What is the formula to find volume of a trapezoid?
The trapezoid is a plane figure which has surface Area, but no volume but if there was a 3d figure your equation would be. The Surface Area of a trapezoid = ½(b1+b2) x h X Height of figure.
How do you find a surface area?

How do you calculate the surface-area-to-volume-ratio?
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
