How to change the voice of a sentence into passive voice?

• We can convert a sentence into passive voice by changing the subject of the active voice statement into the object of the passive voice statement. The object of the active voice statement becomes the subject of the passive voice statement.
• We use the past participle form of the main verb in a passive voice sentence.
• A helping verb should be added whose tense should be the same as that of the active voice statement. As the active voice statement above is in past perfect form, hence we use 'had been' in the passive voice statement.
