2184 Rs is  the cost of cardboard required for Supplying 250 boxes of Each kind.​  for Rs4 for 1000 cm² , Dimensions 25cm *20cm *5cm & 15 cm 12 cm 5 cm.

Step-by-step explanation:

The bigger of Dimensions 25cm *20cm *5cm

Surface Area = 2 * (25 * 20  + 25 * 5  + 20*5)

= 2 (500 + 125 + 100)

= 2 * 725

= 1450

smaller of dimensions 15 cm 12 cm 5 cm.

Surface Area = 2 * ( 15*12  + 15*5  + 12*5)

= 2 ( 180 + 75 + 60)

= 2 * 315

= 630

Total Surface Area = 1450 + 630 = 2080 cm²

For all the overlaps , 5% of the total surface area is required extra

= (5/100)2080 = 104 cm²

Surface Area required for one of Bigger + one Smaller = 2080 + 104

= 2184 cm²

cost for 1000 cm²  = 4

cost for 2184 cm²  ( 1 box of Small & Large) = 4 * 2184 /1000

Cost for 250 boxes of Each kind = 250 * 4  * 2184 /1000

= 2184 Rs

Answer:

Step-by-step explanation:

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
