Answer:
1000
Step-by-step explanation:
Total Cost of tiles = Cost of one tile * No of tiles required
No of tiles required = Total area of wall / Area of 1 tile
Area of one tile = 12 * 10 = 120 cm²
1 m = 100cm, 3m = 300cm and 4m = 400cm
Area of the wall = 400 * 300 = 120000cm²
No of tiles required = 120000/120 = 1000 tiles
