The exterior wall of a house is composed of a 20 cm thick layer of ordinary brick (conductivity 0.72 W/m K) and a 2.5 cm layer of plaster (conductivity 0.17 W/m K ) on each side (two layers in total). Other purely conductive resistances can be neglected, such as the layer of paint on both sides of the wall. Assume the outer face of the wall is at 35 °C and the inner face is at 20 °C and fill in the gaps. The magnitude of the heat flux through the wall corresponds to the _________ W/m2 and is perpendicular to the wall ________________ (fill in with "outside-in" or "inside-out") of the environment. If the wall has a total area of 300m2, the heat transfer rate corresponds to ___________________

Question
The exterior wall of a house is composed of a 20 cm thick layer of ordinary brick (conductivity 0.72 W/m K) and a 2.5 cm layer of plaster (conductivity 0.17 W/m K ) on each side (two layers in total). Other purely conductive resistances can be neglected, such as the layer of paint on both sides of the wall. Assume the outer face of the wall is at 35 °C and the inner face is at 20 °C and fill in the gaps. The magnitude of the heat flux through the wall corresponds to the _________
W/m2 and is perpendicular to the wall ________________
(fill in with "outside-in" or "inside-out") of the environment. If the wall has a total area of 300m2, the heat transfer rate corresponds to ___________________
