The topic is coefficient of linear thermal expansion.

You need the coefficient for steel which comes from

a table. In the future try this one:

http://en.wikipedia.org/wiki/Coefficient_of_therma...

The value given is 11-13×10^-6/°C

The solution is straightforward multiplication.

I'll use 12×10^-6 for marine steel.

408m × 12×10^-6/°C×(26°C-3.59°C) = 109.7194 mm (11cm)

It sounds utterly fascinating,and you could even write a book based on that, but what's the question ?
