What is the formula for a triangular prism

A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.

A triangular prism is a three-sided prism with three faces joining corresponding sides. The formula for its surface area is SA = wh + lw + lh + ls, where l=length, h=height, w=width and s=side.

its not i dont no why

Length of prism * perimeter of triangular face.
