Question

Eight cuboidal metal boxes with dimensions 60cm *45cm*30cm are to be painted. If the rate of painting is RS 200 per meter square , find the total cost of painting

Answer 1

Answer:

Ratio. 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)

=11700cm²

TSA of 8boxes=11700*8

=93600cm²

In m²=93600/100=936m²

Rate of painting =Rs. 200/m²

Cost of total painting =936*200

=Rs. 187200
