![]() If the triangle base is equilateral or the prism is called an equilateral triangular prism with each side 'a', then its area is √3a 2 /4 square units.Here b is the base length, h is the height of the triangle and l is the length between the triangular bases.įormulas to find the Base Area of different trianglesįollowing are the formulas used to find the base area of different types of triangles. Volume of triangular prism = ½ x b x h x l = ½ bhl The base area = ½ bh, where b is the base length and h is the height of the triangle. Since the prism base is in triangular shape, ![]() Volume of a triangular prism = area of base triangle x height The volume of a triangular prism can be calculated by taking the product of the height of the prism and the area of the triangular base. It is measured in cubic units such as cm 3, m 3 etc. In simple words, the volume of a triangular prism refers to the space inside it. The volume of a triangular prism is the space occupied by it from all the three dimensions. The height (h) of the triangular prism is the perpendicular distance between the centres of the two parallel bases. A prism is called a regular or uniform triangular prism if its sides are squares and bases are equilateral. If the sides of the prism are rectangular, it is called a right triangular prism and otherwise it is called an oblique triangular prism. The two triangular bases of the prism are parallel and congruent to each other. The edges and vertices of the prism base are joined with one another via the three rectangular sides. It can also be considered a pentahedron, as it has five faces. Step 4: Write the final value in appropriate square units.A triangular prism is a polyhedron having two triangular bases and three rectangular faces.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. Thus, the lateral area of a triangular prism is the sum of the side faces, that is the three rectangular faces. 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? 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. What Is the Meaning of the Lateral Surface Area of a Triangular Prism? 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. The lateral faces of a triangular prism are rectangles. FAQs on Lateral Area of Triangular Prism What Are the Lateral Faces of a Triangular Prism?
