Measure of marble tile = 15 cm × 20 cm

Size of wall = 4 m × 6 m = 400 cm × 600 cm

So we get area of tile = 15 cm × 20 cm = 300 cm²

Area of wall = 400 cm × 600 cm = 240000 cm²

No. of tiles required to cover the wall = Area of wall/ Area of one tile

Substituting the values

No. of tiles required to cover the wall = 240000/300 = 800 tiles

Hence, 800 tiles are required to cover a wall of size 4 m × 6 m.
