How many types of float are mentioned, and what are they?
One type: Free Float
Two types: Free Float and Total Float
Three types: Free Float, Total Float, and Extra Float
Four types: Initial Float, Free Float, Total Float, and Final Float
What is the formula for calculating "Free Float"?
Free Float = EST at End of activity - (EST at start + Duration of activity)
Free Float = (EST at start + Duration of activity) - EST at End of activity
Free Float = Total Duration - EST at End of activity
Free Float = EST at start + Duration of activity
What is the formula for calculating "Total Float"?
Total Float = Activity’s LFT - (Activity’s EST + Activity’s Duration)
Total Float = (Activity’s EST + Activity’s Duration) - Activity’s LFT
Total Float = Activity’s Duration - Activity’s LFT
Total Float = Activity’s EST + Activity’s Duration
What is the formula for calculating Free Float as shown in the image?
Free Float = (EST at End of activity) - (EST at start + Duration of activity)
Free Float = (EST at start + Duration of activity) - (EST at End of activity)
Free Float = (LFT - EST at End of activity) + Duration of activity
Free Float = (Duration of activity + EST at start) / (EST at End of activity)
