Notes on Surface Area of prisms



Prism: is a space figure that has flat polygon surfaces (faces). Two of the faces (the bases) are parallel and congruent (they can be any polygon. The other faces are parallelograms.









 




Euler’s Formula: Edges = Faces + Vertices – 2

Surface Area: This is the area of all the shapes that make up the entire prism.

For example, this rectangular prism has 6 sides, the bases are two squares, each of the sides is a rectangle. To find the surface area, you must find the area of each face and add it up.

Text Box: Add them all up to find the surface area

Text Box: This figure consists of 6 rectangles:
Top 10 in X 5 in. = 50 in2
Bottom 10 in X 5 in. = 50 in2
Left side 5 in X 25 in. = 125 in2
Right side 5 in X 25 in. = 125 in2
Back 10 in X 25 in. = 250 in2
Front 10 in X 25 in. = 250 in2
Total surface area = 850 in2
