The surface area of an isosceles triangular prism is the number of unit squares that can fit into it. Now, the surface area of an isosceles triangular prism is, SA = Area of the two isosceles triangles + Area of the three rectanglesįAQs on the Surface Area of Isosceles Triangular Prism What is the Surface Area of Isosceles Triangular Prism? Thus, the lateral surface area of an isosceles triangular prism is LSA = 2la + lb. Therefore, the total area of the three rectangles = 2la + lb Thus, the area of the third rectangle = l × b Let the length of the third rectangle is "l" units and the breadth of the third rectangle = 'b' units
Thus, the area of the two congruent rectangles = 2 × l × a Let the length of the congruent rectangles is "l" units and the breadth of the congruent rectangles is "a" units. So let's first find the area of the 2 congruent rectangles: Since we already know that in an isosceles triangular prism, there are 2 congruent rectangles. ⇒ Area of two isosceles triangles = 2 × 1/2 × b × h = b × h Let us consider an isosceles triangle with the equal sides be "a" units, the base of each of the triangle be "b" units and the height of the triangle is "h"Īrea of an isosceles triangle = (1/2 × base × height) = 1/2 × b × h The surface area of the isosceles triangular prism is found as SA = Sum of areas of 2 isosceles triangles at the bases + Sum of the areas of the 3 rectangles. The lateral area of an isosceles triangular prism is found as Lateral area, LA = Sum of the areas of all the vertical faces = Sum of the areas of the three rectanglesĭerivation of Surface Area of Isosceles Triangular Prism Since we know that the vertical faces in the case of an isosceles triangular prism are rectangles, therefore, to find the lateral area we will have to find the areas of all the vertical faces and then add them up. Lateral Area refers to the total area of the lateral or vertical faces of any solid. ⇒ SA = Sum of areas of 2 isosceles triangles + Sum of the areas of the 3 rectangles The surface area of an isosceles triangular prism is found as SA = Sum of areas of all the faces To find the surface area of an isosceles triangular prism, we will have to add the areas of the 2 isosceles triangles at the base facing each other and the area of the rectangles formed by the corresponding sides of the two congruent triangles. The surface area of an isosceles triangular prism refers to the sum total of the area of all the faces of an isosceles triangular prism. Triangular Prism Formulas in terms of height and triangle side lengths a, b and c: Volume of a Triangular Prism Formulaįinds the 3-dimensional space occupied by a triangular prism.Formula for Surface Area of Isosceles Triangular Prism Significant Figures: Choose the number of significant figures or leave on auto to let the calculator determine number precision. Answers will be the same whether in feet, ft 2, ft 3, or meters, m 2, m 3, or any other unit measure. Units: Units are shown for convenience but do not affect calculations. Height is calculated from known volume or lateral surface area. Surface area calculations include top, bottom, lateral sides and total surface area. This calculator finds the volume, surface area and height of a triangular prism. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles. B = side length b = bottom triangle base bĪ lat = lateral surface area = all rectangular sidesĪ bot = bottom surface area = bottom triangleĪ triangular prism is a geometric solid shape with a triangle as its base.
