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?
How many tiles are in one row? ** 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
How many rows of tiles are there? ** 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
How many tiles does Kimiko need to buy? ** 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
