You can put this solution on YOUR website!

It is good  (I'd say  "VERY  GOOD")  that you do react on my notices and change your condition  "step by step".

Now,  let's make the next step forward to take off other deficiencies. 

    From the condition, take off mentioning in the first part, that the iron pipe has the length 12 cm  and simply say 

    that the pipe has a rectangular section with the outer dimensions 12 cm and 10 cm.  

    Then re-post this new version to the forum.


Then all deficiencies will go out,  and the problem will be open for the solution.

When I get this new version from you,  the same day you will get the solution from me.
