Thank you all for your replies, @MR chestermiller it seems pretty complicated to do.a 2d analysis. @Russ waters, yes maybe i should just ask the questioner. The book writes K is transport through a flat wall with a surface area, which does not answer my question yet. The previous question is...

Let's just say there is no uncertainty, because the values are given. If you take the in- or the outside surface area, it has a large impact on the outcome. Especially with thick walls. So my question is, in this formula, should the in- or the outside surface area be used?

Hello To calculate the heat loss of a fridge, do I need to take the surface area of the in- or outside of the fridge? Heat loss formula = k * delta T * A k = heat transmission coefficient A = surface area
