Answer 1

Answer:

We need to use the formula of surface area of a cuboid=2(lb+bh+lh)

Step-by-step explanation

Surface area of big box =2(300+75+100)=950cm^2

Than the area of small box

2(lb+bh+lh)

2(192+48+64)=2×304=608cm^2

Here 608+950=1558cm

If the cost of 1cm cardbod is 20 r

Than the cost of 1558 cm cardbord is

1558×20=31160rupee

And 5percent extra cardbord use 5/100×1558= 77.9cm extra required
