Answer:

good evening dear pls mark as brilliant

Step-by-step explanation:

We need to calculate the total surface area of the cuboid to solve this question.

Total surface area of a cuboid of length l, breadth b and height h =2(l×b+b×h+l×h)

So, the total surface area of the cuboid =50cm=2(40×30+30×50+40×50)

=2(1200+1500+2000)=9400cm

2

Total surface area of 20 boxes =20×9400cm

2

=188000cm

2

=18.8m

2

Total cost =Rs45×18.8m

2

=Rs846
