To find surface area you need to find the area of each side on the shape then add it all together. So for the triangle you need to do 1/2 BxH then multiply the number by 2 because you have 2 triangles. Next you can work out the base LxW then to work out the side you do HxL. Your basically just working out the total area of each side that’s possible to touch, every single side.
