What's the formula for finding the surface area of a prism and the formula for the surface area of a triangular prism??

the surface area of any prism is the total area of all its sides and faces. A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height.

The formula  A=1/2 bh
