Thank you for the opportunity to help you with your question!

linear thermal expansion coef Fe 11.8e-6 /K 

∆L/L = α∆T, α is linear thermal expansion coef
∆L = αL∆T

∆L = αL∆T = (11.8e-6 /K)(51800 cm)(46K) = 28 cm

Please let me know if you need any clarification. I'm always happy to answer your questions.
