Answer 1

Answer:

Rs.4,464/-

Step-by-step explanation:

Surface area=2(lb+lh+bh)

                    =2*[(15*9)+(15*6)+(9*6)]

                    =2*(135+90+54)

                    =2*279

                    =$558m^{2}$

Cost of 1$m^{2}$=Rs.8

Cost of 558$m^{2}$=558*8

                       =Rs.4,464
