First figure out how many tiles are in one row by dividing the kitchen's width by each tile's width: 48 inches / 6 inches / tile = 8 tiles in one row. Then figure out how many rows of tiles there are by dividing the kitchen's height by each tile's height: 72 inches / 6 inches / tile = 12 rows of tiles. Then multiply the number of rows by the number of tiles per row to find the total number of tiles Kimiko needs to buy: 8 tiles / row * 12 rows = 96 tiles.
Therefore, the answer is 96.
