![]() ![]() ![]() 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. Solved example Example: Calculate the surface area of a triangular prism with side 7 cm, base 5 cm and height 6 cm. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Surface area of Triangular Prism (b h) + (L (s1 + s2 + s3)) Where, b is the bottom edge of base triangle, L is the prism length, h is the height of base. Prisms are essential in geometry, helping us understand volume, surface area, and shapes. If you're trying to find the surface area of a triangular prism, use the formula SA 2a + ph, where a is the area of the triangle, p is the perimeter, and h is the height. What sets them apart is their consistent shape along their length, which can be different types of polygons, like triangles, squares, or rectangles. To find surface area for a rectangular prism, use the formula SA 2ab + 2bc + 2ac, where a is the width, b is the height, and c is the length. Units: Note that units are shown for convenience but do not affect the calculations. Prisms are basic 3D shapes that have two flat ends and rectangular side faces.
