Hello,

I am trying to figure how much aluminium sheets would a - 86x12 meter and 4 meter draft - ship need ? It would be a monohull as well.

Thank you,

Can you clarify what the price means? Also, a square meter of any material only covers a square meter.

The price signifies that on a 5 year period aluminium 5000 (noted : A5000) is noted to cost \$2,311 per tonne. However, I have calculated that it would cost, in theory, \$85,507 . So, for that price you can cover a rectangle (dimensions : 84x12x4) of aluminium 5082.

This is how I've come to that conclusion :

calculating the surface area of each side, so
84x12 = 1,032m² for one side -> 2 sides = 2,064m²
12x4 = 48m² -> 2 sides = 96m²
86x4 = 344m² -> 2 sides = 688m²

Total surface area = 2,848 m², and again this is based on a rectangle so it stands as a theoretical value.
Then, I've noted that one single sheet of A5000 is equal to : 5,56m².
Therefore -> 2,848 / 5,56

So, in theory I would need approximately : 512,23 sheets of A5000. To add , one sheet (size 60"x144") = 71,39kg.
Thus making the total weight : 512,23 x 71,39 = 36,568 kg or approximately 37 tonnes.

Finally, as I mentioned earlier the price per tonne is -> 1t = \$2,311. So, we can calculate : 37 tonnes x \$2,311 = \$85,507
So the theoretical price will be : \$85,507.
