Lateral surface area of cuboid: The lateral surface area of a cuboid

The lateral surface area of a cuboid is given by 2 (length + breadth) × height. Similarly, the lateral surface area of a cube of side “a” is equal to 4 × (side) 2. The total surface area of the cuboid is obtained by adding the area of all the 6 faces while the lateral surface area of the cuboid is calculated by finding the area of each face excluding the base and the top. Here you will learn formula for surface area of cuboid (total surface area and lateral surface area ), its derivation and examples based on it. Let’s begin – What is Cuboid ? A cuboid is a three dimensional box. It is defined by the virtue of its length l, breadth b and height h. It can be visualised as a room which has length, breadth and height differerent from each other. Formula for Surface Area of Cuboid (a) Total Surface Area of Cuboid (T.S.A) T.S.A = 2 (lb + bh + hl) (b) Lateral ...
