What is the formula to finding the surface area of a triangular prism? |
To find the surface area of any polyhedron (cube, prism, etc) just add the area of the faces.
A triangular prism has 2 triangular faces and 3 rectangular faces. If the triangular faces are the same size and so are the rectangular, the total surface area will just be 2
(area of triangle) + 3(area of rectangle).
Hope this helps!
