The sum of surface areas of all sides except top and bottom face of solid is defined as lateral surface area of a solid.
Lateral surface area of the cuboid=2h(l + w)
(Note: h=height, l=length, w=width of cuboid)
Example :The length, width and height of a cuboid are 12 cm, 13 cm and 15 cm respectively. Find the lateral surface area of a cuboid.
Solution:
Lateral surface area of a cuboid is given by:
LSA = 2h ( l + w )
Insert the values into the formula,
LSA = 2*15 ( 12 + 13 )
LSA = 750 cm2
