Surface Area For A Triangular Prism Formula. Work out the area of the triangles at the front and back. A triangular prism has three rectangular sides and two triangular faces.
A= hb/2 (half of the base times height, thats the formula for a triangle, i dont have time to give you the other formulas but i hoped this helped.
We know that surface area of a triangular prism is: (3 m, 4 m, 5 m). Volume and surface area of triangular prism a prism with the triangle as the base is called triangular prism. The only option when you can't calculate triangular prism volume is having given triangle base and its height (do you know why?
