Explanation / Answer

steel = 13 10^-6 / °C

T = 870 - 22 = 848
thick
L = L°**T = 25.5*12*10^-6 *848 = - 0.259m
thick 22° = 25.5 - 0.259 = 25.241 cm

Wide
L = L°**t = 2.01*12*10^-6 *848 = 0.02045 m
wide 22° = 2.01 - 0.02045 = 1.9896 m

long
L = L°**t = 10*12*10^-6*848 = 0.10176 m
long 22° = 10 - 0.10176 = 9.8982 m
