![]() ![]() Use the image as a guide for understanding the formula. ![]() ![]() There is a different surface area formula for each shape. The calculator above can easily find the surface area for a shape, but you can also find it using a formula. Find the areas of each of the three rectangular faces, using the formula for the area of a rectangle: length x width. The total surface area of a triangular prism is the sum of the lateral surface area and twice the area of the triangular base. Return to the Object Surface Area section BookMark Us It may come in handy. Edge a Edge b Edge c Height h Surface area For help with using this calculator, see the object surface area help page. The volume is equal to the product of the length of the prism and the area of the triangular base. Surface Area of a Triangular Prism Fields marked with a star () are required. If your measurements are in different units, convert each measurement to the same unit first, then use the formulas below to solve. Here are the steps to compute the surface area of a triangular prism: 1. The triangular prism is said to be uniform if the triangles at the base are equilateral, and the sides are squares. When calculating surface area, taking all measurements using the same unit of measure, such as inches or feet, is important. This Triangular Prism Calculator is developed to help solve problems in geometry. Total surface area is the area of the whole object, including the curved surface, lateral faces, and the area of the base. We know that (a + b + c) is the perimeter of the base (triangle). Lateral surface area is the area the polygon faces of the object, not including the top and bottom bases. Lateral Surface Area of Triangular Prism Calculator. Lateral Area + + ++3 6 4 6 5 6 18 24 30 72() ()( ) cm2 The total surface area of the triangular prism is the lateral area plus the area of the two bases. the sum of the areas of the three rectangles. The surface area of an equilateral triangular prism is (3a 2 /2) + 3(a × h). The lateral area of the triangular prism is the sum of the areas of the lateral faces i.e. Solution: The side length of the triangle (a) 6 units. An example of a curved region would be the cap area of a hemisphere or capsule. Example 1: Find the surface area of the equilateral triangular prism which has a height of 10 units and a side length of 6 units. There are several types of surface area: curved surface area, lateral surface area, and total surface area.Ĭurved surface area is the area of the curved regions of an object. ![]()
