![]() ![]() ![]() It is the sum of the areas of all the faces of the prism. Surface area of triangular prism is the total area covered by its surface in three dimensional plane. Now that we know what the formulas are, let’s look at a few example problems using them. The formula for the surface area of a prism is (SA2B+ph), where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism. For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm 3 and S in mm 2.īelow are the standard formulas for surface area. The surface area of a triangular prism is the area that is occupied by its surface. We see this in the formula for the area of a triangle, ½ bh. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Units: Note that units are shown for convenience but do not affect the calculations. Online calculator to calculate the surface area of geometric solids including a capsule, cone, frustum, cube, cylinder, hemisphere, pyramid, rectangular prism, sphere, spherical cap, and triangular prism ![]()
