Question

A marble tiles measures 15 cm into 20 cm.
How many tiles will be required to cover a Wall of size 4m into 6m

Answer 1

Answer:

800 Tiles

Step-by-step explanation:Area covered by tiles= l*b (where l=20cm or 0.2m  and b=15cm or 0.15m)

Therefore,

area covered by one tile= 0.15*0.2

area covered by one tile= 0.03m^2

area of wall= l*b (where l=6m and b=4m)

area of wall= 4*6= 24m^2

let us suppose the number of tiles=X

therefore,

0.03X= 24

=> X= 800

therefore, the number of tiles required to cover the wall is 800
