We know that (a + b + c) is the perimeter of the base (triangle). The surface area is expressed in square units. Lateral surface area of triangular prism (LSA) ah + bh + ch (or) (a + b + c) h. ![]() Therefore, the length of a candy bar is 2 inches. The surface area of a triangular prism is equal to the sum of the area of tree lateral surfaces and the two bases. Finding the Surface Area Considering Rectangular Prisms To find the surface area of a cube or of any rectangular prism, one can find the area of each. Find the length of the triangular prism if its base is 6 cm, altitude is 9 cm and the area is 198. 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. Gain a thorough understanding of the surface area of a right triangular. Area of the three lateral faces + Area of the two triangular bases. 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. The area covered by all the faces of a right triangular prism represents the total surface area. Using the formula we have, A bh + 3bl 5 (7) + 3 (5) (8) 35 + 120 155 sq. Example 1: Find the surface area of the triangular prism with the measurements seen in the image. ![]() The following formula can be used to get the base area of a triangular prism:ġ46014 = 2A + (416) x (350) ġ46014 – 145600 = 2A Find the total surface area of a triangular prism if its base is 5 cm, altitude is 7 cm and length is 8 cm. Therefore, the surface area of the given prism is 140 square centimeters.Įxample 2: A triangular prism has a surface area of 146014 square millimeters, a height of 350 millimeters, and a base perimeter of 416 millimeters, find the area of the base of this prism. The following formula can be used to get the surface area of a triangular prism : Example 1: If a triangular prism has a base area of 7 square centimeters, a height of 9 centimeters, and a base perimeter of 14 centimeters, what is its surface area?
