![]() S 1 and S 2 are the three sides of the base triangleĪlso Read: Angle Sum Property of QuadrilateralĪ right triangular prism with equilateral bases and square sides is called a uniform triangular prism. Thus, adding all the areas, the total surface area of a right triangular prism is given by, Lateral surface area is the product of the length of the prism and the perimeter of the base triangle = (S 1 + S 2 + h) × l. Lateral Surface Area = (S 1 + S 2 + S 3 ) × LĪ right triangular prism has two parallel and congruent triangular faces and three rectangular faces that are perpendicular to the triangular faces.Īrea of the two base triangles = 2 × (1/2 × base of the triangle × height of the triangle) which simplifies to 'base × height' (bh). Formula V (1/2) × b × h × l where, b is the triangular base, h is the altitude of the prism, l is the length of prism. Thus, the lateral surface area of a triangular prism is: The base area of a triangular prism is equal to half of the product of the triangular base and its altitude. It is the sum of all the areas of the vertical faces. Example 2: Determine the volume of a triangular prism in which the base of the triangle is 8 inches, the height is 6 inches and the length of the prism is 12 inches. Lateral Surface area is the surface area of the prism without the triangular base areas. According to the volume of triangular prism formula, V B x h By substituting the values, V 12 x 6 V 72 (cm3) So, the volume of the triangular prism is 72 cubic centimeters. S 1, S 2, and S 3 are the three sides of the base triangle Using the formulas for the volume of triangular prism and cube to solve some solid geometry problems. Triangular Prism Volume Formula The volume of a triangular prism can be found by multiplying the base times the height. Calculate the surface area of prisms: rectangular prisms, triangular prisms. Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)ī is the resting side of the base triangle, The volume formula to calculate the volume for a rectangular prism is V. Thus, the formula for the surface area of a triangular prism is: The area of the two triangular bases is equal to The sum of areas of the parallelograms joining the triangular base is equal to the product of the perimeter of the base and length of the prism. The formula of volume of triangular prism is 1/2 b x h x l. What is volume of triangular prism Ans: The volume of triangular prism is equal to the product of base and height of the prism. The surface area of a triangular prism is obtained by adding all the surface areas of faces that constitute the prism. The surface area triangular prism formula formula is 2 A+ PH. ![]() Derivation of Surface Area of Triangular Prism
