Translation:How many architects are in the building?
Trying to understand grammar: In aedificio , meaning in the building, has the form of something called "ablative". In previous exercise was "cum archtecto" , meaning with the architect also in ablative, probably because of the "cum". Can somebody explain what "ablative" means?
I don't know what it means, but the function as described in one of the previous skills is as follows: "Accusative: indicates a direct object. The accusative may also indicate the extent of time or space.".
Also, a later skill expanded upon the use of ablative with prepositions: "ad + Accusative = to
in + Accusative = into
in + Ablative = in
ab/a + Ablative = from
cum + Ablative = with"
