No, it's a simile. An example of a synechdoche would be "All hands on deck," except in those rare cases when one is playing bridge on the deck of a ship and you want everyone to put all of their cards down.
The phrase "dumb as a box of rocks" is a colloquial way of saying someone is not intelligent or very foolish. It implies a lack of mental capacity or common sense.
...a box of rocks. ...a bag of hammers. ...a fence post. ...a Dodo bird.
Her laughter was like opening a treasure box, full of hidden delights.

It means really dumb!
Synecdoche is a type of metonymy
No
The oldest simile for 'as dumb as' is 'As dumb as a doornail'. Others include: As dumb as a wet noodle. As dumb as an unpowered computer. As dumb as a library with no books.
I just had this question in school. It is false, Synecdoche is not a type of irony.
all you got to do kid is tell her she rocks and she will be smart about it ;)
