In the picture you see a total of 4 sub-surfaces. How often do these partial surfaces actually occur in the figure? Calculate the surface of the subsurfaces, add up and multiply with 2.

my answer to a similar question of , in which I also did not calculate the area, but showed her where the body (prism) has areas that she has to calculate herself has been deleted.

So it could be that your answer also disappears because you didn’t calculate the area.

Answers to mathematics are rarely deleted with me and I rarely expect anything.

Yes, I had the confrontation with more often :-). But these are different attitudes on the subject, which cannot be resolved in public debate.

Maybe you go to the first question of @Leyla. There I have complained of an answer, because it’s educationally meaningless.
We agree.

You have:

2 squares 10×10
2 triangles (10, 7 and 8)
2 walls 10×50
2 roof sides 8×50
and 1 floor 10×50

Find out individual, take twice where they are double and then add.

You add the area contents of all simple geometric shapes from which the surface is made.

Simply calculate and add the areas? It’s not hard.
