In this exercise students learn about Lateral surface areas of cube and cuboid and apply formulas 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. Lateral area of a three-dimensional object is the surface area of all its sides, excluding the bases (top and bottom surfaces). In this article, we will learn about, lateral area formulas along with related examples and others in detail.
