A 2.30-cm-thick wood floor covers a 4.0 m x 5.5 m room. The subfloor on which the flooring sits is at a temperature of 16.4 degrees celcius, while the air in the room is at 19.3 degrees celcius. What is the rate of heat conduction through the floor? Use 0.200 W / m x K for the thermal conductivity of wood.

    Nvm. I found the answer :)

    It's 555 W.

    (.200 W/m x K)(22m^2)[(19.3-16.4)/0.0230 m]
