Key concepts
3 concepts
- 1
One way to find the surface area of a rectangular prism is to unfold the prism into a net and find the area of each face.
- 2
The formula for finding the surface area of a rectangular prism is SA = 2B + pH, where B is the area of the base, p is the perimeter of the base, and h is the height of the prism.
- 3
When using the net method, remember to find the area of each face and then add all of the areas together.
