I was confused that why we cannot find CSA then I found that CSA=AREA OF FOUR WALLS only then top and bottom of the box will be uncovered but we need to cover full box and all 6 faces of cuboid that why we will find TSA of cuboid ..

Sir I have a doubt.. sir you've said in this tutorial that if we want to find no. Of sheets than we have to divide one sheet area from whole surface area... It is bounced🙃 can you please explain me in detail?

It's actually TSA, but the formula used is correct
It should com TSA instead CSA.
