Kimiko is retiling her kitchen floor. Each tile is 6 square inches. If her kitchen is 48 inches by 72 inches, how many tiles does Kimiko need to buy?
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 = <<48/6=8>>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 = <<72/6=12>>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 = <<8*12=96>>96 tiles
