Answer 1

Answer:

Area of smaller box and bigger box ={2{lh+bh+lb}+2{lh+bh+lh}}

={2{125+100+500}+2{75+60+180}

={1450+630}

=2080cm²

Area extra cardboard box

=TSA of cardboard * 5%

=2080*5%

=2080*5\100

=104cm³

Total area of cardboard required

=TSA + extra cardboard

=2080+104

=2184cm²

Area of cardboard for 250 boxes

= Area of one box*250

=2184*250

=546000²

Cost of 1000cm²of cardboard=4rupee

Cost of cardboard of 546000cm2

=546*4

=Rupee 2184
