along 120 cm you can place 4, 30cm(x20cm) tiles
it means in the 800cm side you will be able to place 800/20 =40 rows of tiles
so total number of tiles = 40 x 4 =160 tiles
another simple way
no of tiles = wall area/each tile area
= (800 x 120)/ (20 x 30) = 96000/600 = 160

area of each tile =20*30=600 sq cm
area of wall =800*120=96000 sq cm
number of tiles required=96000/600=160
therefore,it requires 160 tiles to cover the wall
i hope that this helps

1. The area of the wall you need to cover is: 800cmx120cm = 96000 cmq;
2. The area of one tile is: 20cmx30cm=600cmq;
3. The number of tiles you need to cover the surface of the wall is: 96000cmq/600cmq=160 tiles.

800 / 20 = 40
120 / 30 = 4
OR
40 tiles X 4 tiles

(800/20) X(120/30)
= 40 X 4
= 160 :)

The wall area is 96000 CM and tiles are 600 CM so divide 96000 by 600 and you need 160 tiles.

800 x 120 = 96000
20 x 30 = 600
96000 / 600 = 960 /6 = 160
Allow for cuts

20 X 30 = 600cm Tiles
800 x 120 - 96000cm
- - - - - - - - - - - - - - - - - - -
Divide the 96000 cm by 600cm
96000 ÷ 600 = 160 cm tiles
The answer is 160 cm tiles
