# How to express dimensions with faire/être

As you explain, it is either 1. faire + value + de + dimension (noun) 2. être + de + dimension (adjective) + value You say ...faire 1 m de profondeur. But you also say ...faire 1 m de long Isn't "longeur" the noun for length and "long/ue" the adjective? So why is it not "...faire 1 m de longeur" instead of "1 m de long"? To me this looks like expressing depth works different from all other dimensions. -- Chris.

Bonjour Claus ! Indeed, while you would use "de long / de large / de haut", for depth you use the noun "de profondeur". Note that the forms "de hauteur, de longueur, de largeur" can also be used (though less commonly), however you can never say "de profond". Thanks to you, I've updated the lesson to reflect these nuances. Merci et à bientôt !

Bonjour Aurélie,  You will see that I also posted a question about this.  You may have updated the lesson but NOT the quiz (the 10 question tests) that include this topic.  Mercia!
