Surface Area of Prisms
Lesson Objective
Students will work with a formula for the surface area of a prism.
Lesson Beginning
In your own words, define surface area.
List 3 real life examples where you would need to find surface area.
Surface Area of Prisms
Surface area of a polyhedron is the sum of the areas of its faces.
The surface area of any prism is the sum of the areas of the bases and the lateral faces.
S = areas of bases + areas of lateral faces
Surface Area of a Rectangular Prism
• SA = 2(lw + lh + wh)
Surface Area of Triangular Prisms
• SA = Area of three rectangles + Area of two triangles
Modeling
