Lateral Surface Area (LSA) of a Cuboid: The sum of the area of the four faces of a cuboid, meaning it doesn’t include the area of the top or base of the cuboid. The formula for the lateral surface area of a cuboid can be expressed as: LS A = 2h(l+ b) Total Surface Area (LSA) of a Cuboid. The lateral surface area of a cuboid is the area occupied by its lateral faces , whereas the total surface area of a cuboid is the area occupied by all its six rectangular faces. Learn how to calculate the lateral surface area of a cuboid using the formula LSA = 2H (L + B). See examples, diagrams and solved problems with answers. 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.
