Temperature Problem

  1. Jan 26, 2008 #1
    An automobile windshield has dimensions of 60 cm by 150 cm. What minimum tolerance in mm is needed to prevent the windshield from breaking if the temperature changes by 200°F? (The linear expansion coefficient of glass is 9×10-6 (oC)-1.)

    I'm thinking of using the area expansion formula but I dont understand the part where it says minumum tolerance in mm...

    A = 2a(Tf-Ti)

    a = alpha = 9x10^-6
