To find the surface area of a triangular prism use the formula Surface Area L 2B where L is the lateral area and B is the area of the base. Length 2 lb bh hl. The formula for the lateral surface area of a sphere is the same as the formula for the surface area of a sphere since it has no bases.
To find the surface area of a triangular prism use the formula Surface Area L 2B where L is the lateral area and B is the area of the base.
It is measured in terms of square units. The formula for calculating the lateral surface area is similar to the surface area formula above but since we are not including the top or base we must remove that part of the formula. The lateral surface area formula is. LSA 2 x l w x h Where LSA Lateral Surface Area of Cuboid l Length w Width h Height The Total Surface Area of the cuboid is the sum of both the curved and the lateral surface areas.
