![]() 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. To find the area of the surface of a prism or. The volume of a triangular prism is the product of its triangular base area and the length of the prism. area of the base or end which multiply by the height or length and the product will be the content. Thus, adding all the areas, the total surface area of a right triangular prism is given by, There are two important formulas for a triangular prism, which are surface area and volume. 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). Thus, the lateral surface area of a triangular prism is: How to calculate the surface area of an oblique triangular prism. Therefore, the surface area of the prism is 208 units 2. ![]() It is the sum of all the areas of the vertical faces. Substituting the values of the base area, base perimeter, and height in the surface area formula we get, Surface area of prism (2 × 48) + (28 × 4) 208 units 2. Lateral Surface area is the surface area of the prism without the triangular base areas. S 1, S 2, and S 3 are the three sides of the base triangle Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)ī is the resting side of the base triangle, Example 1: Find the surface area of the triangular prism with the measurements seen in the image. Area of a parallelogram b ×h 8 ×3 24 Area of a parallelogram b × h 8 × 3 24. 2 Calculate the area of the cross section. Thus, the formula for the surface area of a triangular prism is: Volume of prism Area of cross section × Depth. ![]() 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 surface area of a triangular prism is obtained by adding all the surface areas of faces that constitute the prism. Derivation of Surface Area of Triangular Prism
