Question

Find the capacity of a rectangular cistern in liters whose dimensions are 11.2m × 6m × 5.8 m . Find the area of the iron sheet required to make the cistern.

Answer 1

capacity of cistem=volume of cuboid=length x breathe x height
=11.2x6x5.8m^3
=389.76m^3=389760 litres
area of iron sheet required=2(lb+bh+hl)
=2{(11.2) x6+6x (5.8)+(5.8) x(11.2)} m^2

Answer 2

volume of rectangular cistern = lbh i.e, length x breadth x height
                                               = 11.2m x 6m x 5.8m
                                               = 389.76 cubic meters
                                    but,
                        1 cubic meter=1kl=1 kilo litres=1000 litres
             389.76 cubic meters=389.76kl = 389760 litres
