equation for lateral surface area. Lateral Surface Area Perimeter of the base times the altitude. In short form we write lateral surface area as LSA.
A couple of examples showing how to use the surface area formula to solve some problems. 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. Then find the base area by multiplying the base by the height of the triangle and dividing by 2.
The formula to use to find the surface area of cube is 6a 2.
The surface area of the cube is 150 cm 2. The left and right side have side lengths of a and b so the surface area of one of them is ab. Thus the lateral surface area formula looks as follows. The lateral surface area formula is.
