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
