![]() ![]() The height of the triangular prism is H 15 cm. The base and height of the triangular faces are b 6 cm and h 4 cm. Solution: From the image, we can observe that the side lengths of the triangle are a 5 cm, b 6 cm and c 5 cm. Let us solve some examples to understand the concept better. The formula for the surface area of a right triangular prism is calculated by adding up the area of all rectangular and triangular faces of a prism. Example 1: Find the surface area of the triangular prism with the measurements seen in the image. Find the length of the triangular prism if its base is 6 cm, altitude is 9 cm and the area is 198. A triangular prism has three rectangular sides and two triangular faces. Total Surface Area ( TSA) = ( b × h) + ( s 1 + s 2 + s 3) × l, here, s 1, s 2, and s 3are the base edges, h = height, l = length Find the total surface area of a triangular prism if its base is 5 cm, altitude is 7 cm and length is 8 cm. The surface area of any prism is the total area of all its sides and faces. The formula to calculate the TSA of a triangular prism is given below: The area covered by all the faces of a right triangular prism represents the total surface area. ![]() A triangular prism has a triangle as its base, a. It is called a right prism because the angles between the base and faces are right angles. The base and top surface are the same shape and size. The total surface area (TSA) of a triangular prism is the sum of the lateral surface area and twice the base area. A right prism is a geometric solid that has a polygon as its base and vertical faces perpendicular to the base. Lateral Surface Area ( LSA ) = ( s 1 + s 2 + s 3) × l, here, s 1, s 2, and s 3 are the base edges, l = length Total Surface Area The formula to calculate the total and lateral surface area of a triangular prism is given below: The lateral surface area (LSA) of a triangular prism is the sum of the surface area of all its faces except the bases. Example: What is the volume of a prism where the base area is 25 m 2 and which is 12 m long: Volume Area × Length. It is expressed in square units such as m 2, cm 2, mm 2, and in 2. The surface area of a triangular prism is the entire space occupied by its outermost layer (or faces). Like all other polyhedrons, we can calculate the surface area and volume of a triangular prism. To find the area of the triangular faces, use the formula A 1/2bh, where A area, b base, and h height. So, every lateral face is parallelogram-shaped. ![]() Oblique Triangular Prism – Its lateral faces are not perpendicular to its bases.Right Triangular Prism – It has all the lateral faces perpendicular to the bases. Formulas for Surface Area of a Right Triangular Prism.In such a prism, the angle between the connection point at the edges of the base and the top will always be $90^$.
