- 1
The surface area of a triangular prism is the sum of the areas of its two triangular faces and three rectangular faces.
- 2
To find the area of a rectangle, multiply the base by the height, and to find the area of a triangle, multiply the base by the height and divide by two.
- 3
To find the surface area of a triangular prism, first draw the five faces with dimensions, then find the area of each face, and finally add the five areas together.
