Answer:

₹ 187200

Step-by-step explanation:

TSA of cuboid metal box = 2 ( lb + bh + lh )

= 2 [ 60 ( 45 ) + 45 ( 30 ) + 60 ( 30 ) ]

= 2 ( 2700 + 1350 + 1800 )

= 2 ( 5850 )

= 11700 cm²

TSA of 8 boxes = 11700 * 8

                          = 93600 cm²

In m²                  =93600/100

                          =936m²

Rate of painting          = ₹ 200/m²

Cost of total painting  = 936 * 200

                                    = ₹ 187200
