Find the TSA of the tank and then multiply the TSA by the cost per m^2. The answer should be 540 rs.

you need to find the cost of a whole tank so you need to find the total surface area.
length-3m
bredth-2m
height-1.5m
TSA of a cuboid=2(lh+bh+lb)
=2(3x1.5 + 2x1.5 + 3x2)
=2x(4.5 + 3 + 6)
=2x13.5
=27sqm
COST=27x20
=Rs 540
