A 16in x 16 in block has an area of 16*16 sq inches = 16/9 sq feet.
To cover 196 sq ft you will require a minimum of 196/(16/9) = 196*16/9 = 110.25 blocks, that is 111 blocks.
However, this assumes that the area is well behaved and that almost all offcuts are used. In real life that is a very unrealistic assumption and you should allow at least 5% for wastage.
