When changing the voice from active to passive, at first the subject, object, and verb of a sentence must be identified. Then, the tense of the verb must be noted.

The given sentence is in simple future tense and we know that the passive verb form in the simple future tense is made by putting will / shall + be before the past participle form of the verb.
