Answer: Add up the area of all the sides of the figure.
Do you know how to use formulas? :]

Cylinder:
2(pi)rh + 2(pi)r(squared)

Rectanglular Prism:
Just find the area of all the faces of the prism and add them up

Triangular Prism:
Find the area of the two triangular sides and then add it do the rectangular sides.

Basically surface area is just measuring the outside area of a figure.
