Question

a marble tile measures 15 cm × 20 cm how many tiles will be required to cover a Wall of size 4m × 6 m

Answer 1

Answer: 800 tiles

Step-by-step explanation:Area of the wall=4 m×6 m=24 m^2=240000 cm^2

Area of each tile=20 cm×15 cm=300 cm^2

Required number of tiles=Area of wall÷Area of each tile

=240000÷300=800

Answer 2

${Answer :-}$

Here, we have that,
One marble tile = 15 * 20 = 300 cm2.

Size of the wall = 4 * 6 = 24 m2. = 240000 cm2
Since, 1 m2 = 10000 cm2.

So, no. Of tiles required = (240000) / 300 = 800 tiles.

Hence, 800 tiles would be required.
