The brick wall (of thermal conductivity 0.41 W/m · ◦ C) of a building has dimensions of 5.9 m by 4 m and is 16 cm thick. How much heat flows through the wall in a 17.2 h period when the average inside and outside temperatures are, respectively, 14◦C and 3◦C? Answer in units of MJ.
Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way
