Question

If the area of a single ceramic is 0.25 m² ,how many ceramics are used to cover a floor of a classroom whose area is 40m²

Answer 1

To cover a 40 m² floor with 0.25 m² ceramic tiles, you divide the total floor area by the area of one tile, resulting in a need for 160 ceramic tiles.

Step-by-step explanation:

The student asked how many ceramic tiles, each with an area of 0.25 m², would be needed to cover a classroom floor of 40 m². To solve this, we simply divide the total area of the classroom floor by the area of a single ceramic tile. So, the calculation would be 40 m² divided by 0.25 m². Here is how you can do it step-by-step:

1. Find the area of one ceramic tile, which is given as 0.25 m².
2. Find the total area of the classroom that needs to be covered, which is given as 40 m².
3. Divide the total area of the classroom by the area of one tile to get the number of tiles needed: 40 m² / 0.25 m² = 160.

Therefore, 160 ceramic tiles are needed to cover the floor of a classroom.
