Physics Confused HELP PLEASE! A 2.4-cm-thick wood floor covers a 4.0m×5.5m room. I'll give best answer.?

Question

The subfloor on which the flooring sits is at a temperature of 16.2 ∘C, while the air in the room is at 19.2 ∘C. What is the rate of heat conduction through the floor? Use 0.200 W/m⋅K for the thermal conductivity of wood.
P=_____W

peterpan · Accepted Answer

P = k S ΔT / d
where
k = 0.200 W/(m K)
S = surface
d = thickness
then
P = 0.2 *(4*5.5) * 3 / 0.024 = 550 W
