What is the surface area and volume of a triangular-based pyramid?

Volume_any_pyramid = 1/3 × area_base × perpendicular_height For a triangular pyramid (tetrahedron) this becomes: volume = 1/6 × base_width × base_height × pyramid_height For the surface area there is no (easy) general formula: the area of the base triangle and the area of the three side triangles need to be worked out and added together.

What is the difference between total surface area and lateral surface area?

total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
