How to calculate activity duration as the sum of multiple resource assignment's durations?

How to calculate the sum of all the resource assignment durations to determine the total hours all resource assignments must work on an activity?

Activity duration is the duration between the earliest resource start date and the latest resource finish date. It is not the sum of all the resource durations.

If resources overlap, the Activity duration is not the sum of all the Resource durations.
