Area of each tile = 6 ft * 6 ft = 36 square ft
Area to be covered = 325
Number of tiles required = 325/36 = 9.03 = 10
That is the mathematical answer. In real life the number of tile required will depend on how "well-behaved" the shape is, what proportion of offcuts can be used.

As 8 feet x 8 feet = 64 square feet it will only take one 8 feet by 8 feet tile to cover 64 square feet.

192 tiles
16x16 square feet = 256 square feet, so two tiles will suffice.
A 2ft x 2ft square is 4 square feet and 42 squares will be needed to cover 168 square feet.
