Answer:
if the box is OPENED then we LSA OF CUBOID should be applied here.
AREA = LSA(area of four walls)+ area of base
AREA= 2 ( l + b ) h + l × b
= 2 ( 28 + 0.5 ) 0.2 + 28 × 0.5
= 2 × 28.5 × 0.2 + 28 × 0.5
= 11.4 cm^2 + 14 cm^2
= 25.4cm^2

Answer:
Lateral surface Area of cuboid = 2h ( l + b ) + lb
Given dimensions:
Length = l = 28 units
Breadth = b = 0.5 units
Height = h = 0.2 units
Area required = 2 × 0.2 ( 28 + 0.5 ) + 28 × 0.5
= 0.4(28.5) + 14.0
= 11.4 + 14
= 25.4 units
