![]() The measurements on the triangular prism are in mm therefore the total surface area of the triangular prism 144mm2 144mm2. There are two full D 3h symmetry facetings of a triangular prism, both with 6 isosceles triangle faces, one keeping the original top and bottom triangles, and one the original squares. 24+24+24+32+40144 24 +24 +24 +32 +40 144. 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 volume of a truncated triangular prism with base area A and the three heights h 1, h 2, and h 3 is determined by (+ +). ![]() Surface Area 96 + 96 + 180 + 240 + 300 912 square units: The work that was done in the example above can be combined to reveal a 'formula' for the surface area of a right prism. Use our online triangular prism calculator to find the surface area within a blink of eye. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. The surface area of this right triangular prism is the sum of the areas of all 5 faces. Surface Area ( Base × Height ) + ( ( Side1 + Side2 + Side3 ) × Prism Height ) 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. Units: Note that units are shown for convenience but do not affect the calculations. Heres the most basic formula for triangular prism surface that we can use: Area Length × (a + b + c) + (2 × Base area) or.
