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
