Detailed Solution

Lateral surface area of the cuboid is the area of the cuboid with non-base faces.
The Lateral surface area of cuboid can be given as,
LSA=2(hl+hb)
LSA=2h(l+b)
Where,
h = Cuboid height
l = Cuboid length
b =Cuboid breadth
Hence, lateral surface area of the cuboid = 2 height (length + breadth)
Option 1 is correct.
