Answer 2

length (l) of box = 1.5m

Breadth (b) of box = 1.25 m

Depth (h) of box = 0.65m

(i) Box is to be open at top

Area of sheet required.

= 2lh+2bh+lb

= [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 m2

(ii) Cost of sheet per m^2 area = Rs.20.

Cost of sheet of 5.45 m^2 area = Rs (5.45×20)

= Rs.109.
