Answer:
Given:
Length of box =1.5 m, Breadth =1.25 m, Height =0.65 m
⇒Area to be white-washed = Area of cuboid − Area of base.
(i) Area of sheet requred =2lb+2bh+2lh−lb
(i) Area of sheet requred =2lh+2bh+lb .[Box is open]
=[2×1.5×0.65+2×1.25×0.65+1.5×1.25] m
2
=(1.95+1.625+1.875)m
2
=5.45 m
2
ii) Cost of sheet per m
2
area = Rs. 20
Cost of sheet of 5.45m
2
area = Rs. 5.45×20
= Rs. 109
