Calculating Area and Dimensions

The video tutorial explains how to determine the number of 2x2 inch Post-it notes needed to cover a 20x10 inch whiteboard. It involves calculating the area of a single Post-it note and the entire whiteboard, then dividing the total area of the whiteboard by the area of one Post-it note to find the number of notes required. The solution shows that 50 Post-it notes are needed to cover the whiteboard completely.
