Rodrigo class also plans to make a wall mosaic with an are of 0.5m square.how many 1cm square tiles will they need for this 0.5m square mosaic

a square m is 10000 square cm

How many square cm are there in 1 square metre?

- then how many in 1/2 square metre ?

To find out how many 1cm square tiles are needed for a 0.5m square mosaic, we first need to convert the measurements to the same unit.

1 meter (m) = 100 centimeters (cm)

So, the area of the mosaic in centimeters will be:

0.5m * 100cm/m * 0.5m * 100cm/m = 2500cm^2

Now, we divide the total area (2500cm^2) by the area of each 1cm square tile to find out the number of tiles needed.

Number of tiles = Total area / Area of each tile

Since each tile is 1cm x 1cm, the area of each tile will be 1cm^2.

Number of tiles = 2500cm^2 / 1cm^2 = 2500 tiles

Therefore, Rodrigo's class will need 2500 1cm square tiles to create the 0.5m square mosaic.
