Cisterns are cuboidal in shape.
dimension = 11.2m x 6m x5.8m
capacity = volume = lbh = 11.2m x 6m x5.8m = 389.76 m3
1 m3= 1000l
So capacity = 389.76x1000 = 389760 Litre
area of iron sheet required = total surface area of cistern
= 2(lb+bh+lh)
= 2(11.2x6 + 6x5.8 + 11.2x5.8)
= 2(166.96) m2
= 333.92 m2
capacity = 389.86 m3
area of sheet required = 333.92 m2
