![]() ![]() Therefore, the length of a candy bar is 2 inches. The following formula can be used to get the base area of a triangular prism:ġ46014 = 2A + (416) x (350) ġ46014 – 145600 = 2A 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. ![]() Find the lateral surface area of a rectangular prism whose length is 9.5 cm, width is 8 cm, and height is 4 cm. Find the areas of each of the three rectangular faces, using the formula for the area of a rectangle: length x width. Now, that we have seen the formula and method to calculate the surface area of a square prism, let us have a look at a few solved examples to understand it better. Here are the steps to compute the surface area of a triangular prism: 1. Thus, the total surface area of a square prism is 2s 2 + 4sh and the lateral surface area is 4sh in squared units. Solution: As we know, Total Surface Area (TSA) 2 (lw + wh + hl), here l 15 m, w 7 m, h 5 m. Thus, the total surface area of a square prism is 2s2 + 4sh. The following formula can be used to get the surface area of a triangular prism : Find the surface area of a rectangular prism given in the figure. ![]() 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? ![]()
