I did this right but am still unclear as to the difference between the classifiers
cái and chiếc. Would you please explain?
can we also say "tôi ăn cái bánh với một cái muỗng"?
Could voi be used in the sentence?
Yes. Với can be used as bằng as a means of actions
Yes but với in this case could also mean "(cake) as well as (another food)".
