Question

A marble tile measure 12cm × 10cm. How many tiles Will be required to cover a wall of size 4m×6m

Answer 1

Area of the marble tile= 12×10 cm

Area of wall = 4 × 6 m or 400× 600 cm ( 1m = 100cm)

Area of wall= n × area of one tile. ( n = number of tiles)

Therefore, 400× 600= n× 12× 10 cm

400 × 600/12× 10 = n

5× 400= n

n= 2000

The number of tiles required are 2000.
