Final answer:
To cover the entryway, it will take 2400 tiles.
Step-by-step explanation:
To find out how many tiles are needed to cover the entryway, we need to calculate the total area of the entryway and divide it by the area of each tile.
Given that each tile is 5 cm by 5 cm, the area of each tile is 25 square cm.
To convert the area of the entryway to square cm, we multiply it by 10,000 (since 1 square meter is equal to 10,000 square cm).
Therefore, the total area of the entryway is 6 * 10,000 = 60,000 square cm.
Finally, we divide the total area of the entryway by the area of each tile (60,000 / 25) to find the number of tiles needed. So, it will take 2400 tiles to cover the entryway.
