Question

Put this on the table active voice changed to passive voice

Answer 1

the answer to ur question is =>

let this be put on the table

OR

you are ordered to put this on the table

since , this is an imperative sentence (an order) , we can use let or the words like ordered , instructed . Although the word ordered is most suitable whenever there is an ordering statement

when there is a request in an imperative sentence , the most suitable word is requested

and when there is an advice in imperative sentence then , the most suitable word is suggested or adviced
hope this helps

Answer 2

As being an imperative sentence the passive of it will be like this-"You are ordered to put this on the table." Hope this will be right.
