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?
To find out how many tiles Kimiko needs, we first need to calculate the total area of her kitchen floor in square inches.
The area of the kitchen floor is given by the length multiplied by the width:
Area = Length × Width
So, for Kimiko's kitchen:
Area = 48 inches × 72 inches
Now, let's calculate:
Area = 48 inches × 72 inches = 3456 square inches
Now, we need to find out how many 6-square-inch tiles can fit into this total area. We can do this by dividing the total area by the area of each tile:
Number of tiles = Total area / Area of each tile
Number of tiles = 3456 square inches / 6 square inches per tile
Number of tiles ≈ 576
So, Kimiko needs to buy approximately 576 tiles to retile her kitchen floor.
