![]() ![]() ![]() ![]() To recall, the surface area of an object is the total area of the outside surfaces of the three-dimensional object i.e, the total sum of the area of the faces of the object. the formula for the total surface area is 2 (pi)radius (height) + 2 (pi). In such a prism, the angle between the connection point at the edges of the base and the top will always be $90^$. Surface area formulas in geometry refer to the lateral surface and total surface areas of different geometrical objects. pyramid, and rectangular/triangular prism. It is determined with the formula: Surface area bh + L (s1 + s2 + s3) where, b is the bottom edge of the base triangle, h is the height of the base triangle, s 1, s 2, and s 3 are the sides of the triangular bases.

Surface area of a triangular prism is the sum of the areas of all the faces of the prism. ![]()
