Step-by-step explanation:

Passive voice is a form or set of forms of verbs in which the subject undergoes the action of the object.

Passive voice is used, when;

1: We don't exactly know the subject of the action e.g. A snake was killed. (We don't know, who killed the snake), the trees were cut (who cut them, no idea)

OR

2: When the action itself is more important (want to emphasize action) than subject of the action. For example, A snake was killed by him ( snake being killed is more important or emphasized than who killed the snake).

An easy and short-cut way to identify whether the sentence is a passive voice or not is;

Passive voice always have a form of be (be/is/are/am/was/were) which are followed by third form (past participle) of principal verb. If it is not so, the sentence is certainly not a passive voice. And if it does have this structure the sentence is certainly passive voice.
