this one...​

Answer 1

Answer:

Step-by-step explanation:

As we know that,

Surface area of cuboid =2(lb+bh+hl)

Therefore,

Surface area of 1 tin box

=2(30×40+40×50+50×30)

=2×(1200+2000+1500)

=9400cm^2

 Surface area of 20 tin box =20×9400=188000cm^2

=18.8m^2

 Given that the cost of the tin sheet is R.20 per square meter.

Therefore,

Cost of tin required for 20 tin boxes =20×18.8=Rs.376
