Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
Whatever the net, the answer is the same area as that of the net.
2*area of triangular base + perimeter of triangle*length of prism.
Area of triangle * 2 + perimeter of triangle * length.
the defnition of find the surface area of triangular prism and cylinder
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.
triangular prism- formula: Abh(area of the base * height)
Length of prism * perimeter of triangular face.
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
Surface area of the triangle x the length of the prism.
