Step 3: Write the obtained answer with square units.Step 2: Now subtract the areas of the triangles at the top and the bottom from the total surface area.Step 1: Identify the given dimensions for the triangular prism.The steps to determine find the lateral area of a right triangular prism if the total surface area is known are: How to Find the Lateral Area of a Right Triangular Prism If Its Total Surface Area is Known? Step 4: Write the obtained answer with units.Step 2: Now substitute the values in the formula, A = 3lb.Step 1: Identify the given dimensions of the right triangular prism and let the length of the rectangular face is "l".The steps to determine the length of the rectangular face if its lateral area is known are: How to Find the Length of the Rectangular Face If Lateral Area of a Right Triangular Prism Is Known? ![]() Step 4: Write the obtained answer with square units.Step 3: Multiply the obtained by 3, as there are three such faces.Step 2: Now determine the area of a rectangular face by multiplying the length and breadth of the rectangular faces.Step 1: Identify the length and breadth of the rectangular faces.The steps to determine the lateral area of a right triangular prism are: How to Find Lateral Area of a Right Triangular Prism? The formula the lateral area of a right triangular prism shows the direct dependence of the area of a rectangular face on it. The formula of the lateral area of a right triangular prism is given as LA = 3lb, where l is the length of the rectangle and b is the breadth of the rectangle. What is the Formula of the Lateral Area of a Right Triangular Prism? For example, it can be expressed as m 2, cm 2, in 2, etc depending upon the given units. What Units Are Used for Lateral Area of a Right Triangular Prism? The rectangular or lateral faces are perpendicular to the triangular bases. Also, the two triangular bases at the top and the bottom are parallel and congruent to each other. A right triangular prism has three rectangular sides which are congruent. The lateral area of a right triangular prism is defined as the number of unit squares that can be fit into a right triangular prism. S 1 and S 2 are the three sides of the base triangleĪlso Read: Angle Sum Property of QuadrilateralĪ right triangular prism with equilateral bases and square sides is called a uniform triangular prism.FAQs on the Lateral Area of a Right Triangular Prism What is the Lateral Area of a Right Triangular Prism? Thus, adding all the areas, the total surface area of a right triangular prism is given by, ![]() Lateral surface area is the product of the length of the prism and the perimeter of the base triangle = (S 1 + S 2 + h) × l. Lateral Surface Area = (S 1 + S 2 + S 3 ) × LĪ right triangular prism has two parallel and congruent triangular faces and three rectangular faces that are perpendicular to the triangular faces.Īrea of the two base triangles = 2 × (1/2 × base of the triangle × height of the triangle) which simplifies to 'base × height' (bh). Thus, the lateral surface area of a triangular prism is: It is the sum of all the areas of the vertical faces. Lateral Surface area is the surface area of the prism without the triangular base areas. S 1, S 2, and S 3 are the three sides of the base triangle Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)ī is the resting side of the base triangle, Thus, the formula for the surface area of a triangular prism is: The area of the two triangular bases is equal to The sum of areas of the parallelograms joining the triangular base is equal to the product of the perimeter of the base and length of the prism. The surface area of a triangular prism is obtained by adding all the surface areas of faces that constitute the prism. Derivation of Surface Area of Triangular Prism ![]()
