see
width is 2
so external dimensions are 16m 13m and 8 m
so the total surface area will be 2 (lb+bh+lh)
the answer can be found by multiplying
2 (lb+bh+lh) × rs 5

Wrong answer
what's the correct one?
I got it..will send the correct answer soon
since the width of sheet is 2m, so surface area will be divided by 2 to get the length of sheet, hence answer will be (lb+bh+lh)×5.
After finding length,in the solution they wrote that cost of iron sheet=length of iron sheet×5.But I didn't understand why did they do this in solution.Please explain me if you can.
I'll just send a picture of the solution
unable to send the pic in comment, try to explain
see the surface area is to be constructed, so total surface area of sheet must be equal to the surface area of the tank, since surface area of the sheet will be equal to the product of the width and length of the sheet and width of the sheet is given I. e. 2m, hence length is to be calculated
