A book was being read by the teacher.

* The given sentence is in the active voice so it needs to be changed into the passive voice.

* In case of active voice, the subject directly performs the action and so the form is:

* In case of passive voice, the subject interchanges its position with the object so it becomes:

Object+ Verb+ Subject

* In this case, the verb is in the past continuous tense which gets changed into the past perfect tense.
