    Explanation:

    Heat = mc(change in temp.)

    m=mass , c = specific heat

    Rate of flow of heat = heat current = kA/L(T2-T1)

    So, mass = density×volume

    So, mc(T2-T1)/time =

    kA/L(T2-T1)

    Substitute the values given as there are a lot of values missing, so the answer can not be obtained.
