Lateral Surface Area of Cuboids

The video tutorial explains how to find the surface area of a cuboid, a three-dimensional shape defined by its length, breadth, and height. It details the calculation of the surface area by summing the areas of the six rectangles that form the cuboid. The concept of lateral surface area is introduced, which involves the sum of the areas of the side rectangles, excluding the top and bottom. The tutorial also highlights a practical application of lateral surface area, such as painting the exterior sides of a house.
