To find the SA of any prism, find the area of each face. (*Note: Depending on the shape of the face, there might be different formulas.

Area of Square=length x length

Area of Triangle=base x height divided by 2

Area of Trapezoid=A1+A2 (divide the trapezoid into two triangles and find the area of each triangle, then add them) )

After you find the areas of all the faces of the prism, add all the areas to get the SA.
