Let the base of a right triangle be 5 units, the height of the triangle be 12 units, the length of a prism be 11 units and the hypotenuse of a right triangle be 13 units. Let us take an example to find the surface area of a right triangular prism. Here, 'h' is the height of the base triangle, S1 is the base edge, S2 is the hypotenuse and L is the base length of the prism as shown in the figure. You can use this formula for any rectangular prism, and you will always get the surface area. Add them all together to get the area of the whole shape: lw + lw + wh + wh + lh + lh. If l, b, and h are the length, breadth, and height of a rectangular prism, then: Its total surface area (TSA) 2 (lb + bh + lh) Its lateral surface area (LSA) 2h (l + b) Prisms are solids with flat parallelogram sides and identical polygon bases. Now youve found the area of each of the six faces. The surface area of a rectangular prism is the total area or region covered by its six faces. The formula to calculate the surface area of a right triangular prism is given as S1 × h + (S1 + S2 + h) L The area of the right face is also 20 square inches. The surface area of a right triangular prism formula is: Surface area (Length × Perimeter) + (2 × Base Area) ((S)1 + (S)2 + h)L + bh. The base is 93.6cm2, and the height is 20 cm. To find the volume of the right hexagonal prism, we multiply the area of the base by the height using the formula V Bh. Answer: The formula to calculate the surface area of a right triangular prism is given by S1 × h + (S1 + S2 + h) LĪ right triangular prism is a three-dimensional solid that has three rectangular sides and two right triangular faces. 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. Then, the surface area of the hexagonal prism is. H: The height of the triangular base of the prism. s 2: The second of two remaining sides (not the designated base) of the triangular base of the prism. s 1: One of the two remaining sides (not the designated base) of the triangular base of the prism. The formulas for LSA and TSA are given as: Total Surface Area of an Equilateral Triangular Prism. We find the sum of areas of all the sides and faces of a right triangular prism to determine its surface area. b: A base of the triangular base of the prism. The formula for the surface area of an equilateral triangular prism is calculated by adding up the area of all rectangular and triangular faces of a prism.
