How much total float does activity F have in a project schedule?

Total float, also known as total slack, is the amount of time that a scheduled activity can be delayed without delaying the project's completion date. To determine the total float for an activity, it's essential to analyze its relationship with other activities in the project schedule, including its early start, early finish, late start, and late finish times.

When an activity has a total float of zero, it means that it is a critical activity—on the project’s critical path—which does not have any leeway in its timing. If it is delayed, the project as a whole will face a delay as well. Activities with zero total float have a direct impact on the completion timeline of the project.

In this case, since the total float for activity F is determined to be zero, it indicates that this activity must start and finish on time according to the project plan. Any delays in activity F will directly affect the project's completion, making it crucial for timely execution.

When considering other options for total float, if activity F had any float (1, 2, or 3 days), it would mean that some flexibility in scheduling exists. However, identifying total float as zero assists in prioritizing project resources and attention toward activities that impact the overall timeline. Thus
