what is the formula for a surface area. Surface Area of a Triangular Prism Calculator Generally the surface area of a triangular prism formula is equal to twice the base area plus the perimeter of the base times the height or length of the solid. In the figure the height is measured from side b to the opposite side b so the area is calculated as b x h not a x h.

Convention calls the side the height is perpendicular to the base In formulas the base is usually denoted with a b. For cones with slant height l and radius r surface area is calculated using this formula. A 4pr² where r stands for the radius of the sphere.
For cylinders with height h and radius r the formula for surface area is.
