![]() Step 4: Write the final value in appropriate square units.Step 3: Put the values of the given dimensions in the formula, LSA = (a + b + c) h or Ph.Step 2: Identify the height of the prism, h.Step 1: Identify the dimensions of the triangular base (the bases of the three rectangular faces) and find the perimeter, P = a + b + c.To calculate the lateral area of a triangular prism, follow the steps given below: How To Calculate the Lateral Area of a Triangular Prism? In order to find the lateral area, put the respective values in the formula and add the unit with the final value so obtained. Thus, we can conclude that the lateral surface area of the triangular prism = Perimeter of the base × Height of the Prism. Also, (a + b + c) is the perimeter of the base (triangle). ![]() The lateral surface area of the right triangular prism (LSA) = ah + bh + ch (or) (a + b + c) h, where a, b and c are the bases of the rectangular faces and h is the common height or the total height of the prism. How to Find the Lateral Area of a Right Triangular Prism? The formula to find the lateral area of a triangular prism is, (a + b + c) h or Ph. The formula takes the area of each of the five faces (two triangles and three rectangles) and adds them together. Thus, the lateral area of a triangular prism is the sum of the side faces, that is the three rectangular faces. The surface area of a triangular prism equation can be used for any triangular prism. We know that the lateral area of any prism is the sum of the areas of its side faces. What Is the Formula To Find the Lateral Area of a Triangular Prism? Volume pyramid 1 3 ( base area) ( height) We also measure the height of a pyramid perpendicularly to the plane of its base. Example 1: finding the surface area of a triangular prism with a right triangle. The lateral area of a prism of height h where the dimensions of the triangular bases are a, b, and c is (a + b + c) h. The lateral surface area of a triangular prism is the sum of the areas of all its side faces which are 3 rectangles. (Apothem length h/2) Where ( According to heron’s formula) The volume of a triangular prism Area of base triangular prism × height. What Is the Meaning of the Lateral Surface Area of a Triangular Prism? Total Surface area of triangular prism 2B + Pl (2 x Triangle area) + ( a + b + c ) l Triangle area B. A triangular prism has 3 lateral faces that are rectangles. Which Polygon Is a Lateral Face of the Triangular Prism?Įach lateral face (side face) of a triangular prism is a rectangle. The "bases" of a triangular prism are the triangles (which are congruent and parallel) that lie on the top and bottom of the prism whereas the "lateral faces" are the side faces (all faces other than the "bases") that are rectangles. How Is a Lateral Face of a Triangular Prism Different From a Base? The base of each of these rectangles coincides with one side of the triangular base. All these rectangles have the same height. Lateral surface area of the prism (Perimeter of the base) × (Height). The lateral faces of a triangular prism are rectangles. of hexagon Perimeter 600 Number of sides 6 100 cm. FAQs on Lateral Area of Triangular Prism What Are the Lateral Faces of a Triangular Prism?
