![]() The lateral surface area of a prism (LSA) is equal to the sum of the areas of its four lateral faces. What is Lateral Surface Area of a Rectangular Prism? The total surface area of a rectangular prism is equal to the sum of the total areas of all its faces. What is Total Surface Area of a Rectangular Prism? Some examples of rectangular prisms that we see in our everyday lives are fish tanks, notebooks, diaries, cargo containers, rooms, etc. What are Some Examples of a Rectangular Prism? It has a total of six faces, twelve edges, and eight vertices. The dimensions of a rectangular prism are length, width, and height. In mathematics, a rectangular prism is a three-dimensional geometric figure that has four lateral faces with two congruent and parallel bases. Determine the surface area of a right rectangular prism if its height is 20 units and the length and breadth of the base are 10 units and 15 units, respectively. Find lateral surface area of a right rectangular prism if the length and breadth of the base are 8 units and 7 units, respectively. If the lateral surface area of the right Rectangualr Prism is 120 sq units and its height is 10 units find the Total surface area of rectangular prism Find surface area of a right rectangular prism if its height is 10 units and the length and breadth of the base are 18 units and 9 units, respectively. Practice Questions on Surface Area of Rectangular Prism Hence, the rectangular prism’s total surface area is 616 square units. Breadth of Rectangular base (b) = 7 units.Length of Rectangular base (l) = 10 units.Hence, the rectangular prism’s surface area is 392 square units.Įxample 5: Determine the surface area of a rectangular prism if its height is 14 units and the length and breadth of the base are 10 units and 7 units, respectively. Total Surface Area of a Rectangular Prism = 2(lb + bh + lh) square units cm.Įxample 4: Determine the surface area of a rectangular prism if its height is 12 cm and the length and breadth of the base are 8 cm and 5 cm, respectively. Hence, the lateral surface of the given prism is 864 sq. Lateral Surface Area of a Rectangular Prism = 2h (l + b) square units Breadth of Rectangular base (b) = 10 cm.Thus, length of the rectangular prism is 7 inches.Įxample 3: Find the lateral surface area of a rectangular prism if its height is 18 cm and the length and breadth of the base are 14 cm and 10 cm, respectively. Now, substitute the given values of length, breadth, and height in the formula. Step 2: We know that the surface area of a rectangular prism is equal to 2(lb + bh + lh) square units. In the given example, the length and breadth of the rectangular prism’s base are 10 units and 6 units, respectively, and its height is 15 units. Step 1: Note the dimensions of the given rectangular prism. ![]() Let us go through an example to understand the concept of calculating the surface area of a rectangular prism.Įxample: Calculate the surface area of a rectangular prism if its height is 15 units and the length and breadth of the base are 10 units and 6 units, respectively. How to Find Surface Area of a Rectangular Prism? So, the formula for calculating the total surface area of a right rectangular prism is given as below, Total Surface Area of a Prism (TSA) = LSA + 2 × Base Area The total surface area of a right rectangular prism is equal to the sum of the total areas of all its faces. Total Surface Area of a Rectangular Prism “ b ” is the breadth of the side of a base.“ l ” is the length of the side of a base.Role of Mahatma Gandhi in Freedom Struggle.
