How many metal sheets of 8 feet by 4 feet will needed to make a 50000 liters tank?

Answer 1

Firstly, convert the litres to cubic feet 50,000 litres = 1,765.7 Divide by 8 (the maximum height of walls 1 sheet high, square area of floor must be 220.7 As the square are of the sheets is 8 x 4 = 32 then we need 6.896 sheets in the base So now we know that a 'floor' made up of 7 sheets. If we line this up with their longest sides touching then we will have a floor 8 feet wide and 7 x 4 feet long. (This will measure 224 sq feet) A wall 8 feet tall on all sides will give a volume of 224 x 8 = 1792 sq feet. This is equal to 50,744 litres (so there's a little space at the top. The ends will each need walls made of need two sheets standing upright and the long sides can each be made of 7 sheets standing upright. so we not have 2 on each end (4) and 2 each on the two walls and the floors (21). This gives a total of 25 sheets. -- NOTE -- I'm presuming that the sheets will be joined by welding which doesn't require overlapping, and not by rivetting, which does. Overlapping would reduce the volume.
