Answer 2

Answer:

698.25

Step-by-step explanation:

the bigger box = 2 ( lb+bh+ hl)

= 2 ( 3x20+20x5+5x3)

2(60+100+15

2(175

=350

350x5/100

= 17•5

=350+17•5

= 367•5cmx250

=9187.5

smaller box

2(15x12+12x5+5x15)

2(180+60+75)

2(315)

=630x5/100

=31.5

=630+31.5=661.5

=661.5x250

=165375cm

=165375+9187.5

=174562.5

cost of cardboard box=rs 4

=174562.5x4/1000

=698.25
