The number of post-it notes will be ≤ 1

Explanation:

The sides of a white board = 1 foot by 1 foot therefore (the area of the board)

= 1 *1 = 1 ft ^2

post- it notes dimensions = 2 inch by 2 inches = 4In^2 ( area of each post-it notes )

Therefore how many post - notes is contained in the board :

1 FOOT = 12 INCHES

therefore 4 INCHES = 0.33 feet
