Conduction Problem

  1. Dec 11, 2011 #1

    Determine the heat loss through a 1m square pane of 6 mm thick glass for a temperature difference of 15oC.
    Thermal conductivity of glass is k = 0.72 W m^-1 K^-1
    Rate of loss of heat = 0.72W m^-1 K^-1 x 1 m^2 x 15oC/(6x10^-3 m )
    <--- Ok so I understand everything but I dont understand where my teacher gets 6x10^-3 ?? is not in the question that number.

    Please help me
