Question

Harry has a floor 8 metres long by 6 metres wide.He tiled the entire floor with square tiles of side 25 cm . How many tiles would be required to tile the floor

Answer 1

Answer:

768 tiles would be required to tile the floor.

Step-by-step explanation:

Let's first calculate the number of square meters that the rectangular floor represents, by using the formula for the area of a rectangle (length x width):

Floor area = 8 m x 6 m = 48 $m^2$

Next, let's convert the side of the square tiles into meters in order to keep the same units in both (floor area an tile area):

25 cm = 0.25 m

Then the are of a square tile can be obtained by the formula 0.25 m x 0.25 m = 0.0625 $m^2$

Now to find the number of tiles needed, we perform the division of the total floor area to be covered divided by the area covered by a single tile:

Number of tiles needed: 48 $m^2$ / 0.0625 $m^2$ = 768  tiles
