The floor is also 3000 cm long and 2000 cm wide.
100 of the 20 cm tiles will cover the width.
150 of the 20 cm tiles will cover the length.
15,000 will cover the floor (the product)
====
Check by area:
a tile has 0.2*0.2=0.04 m^2
The floor area is 600 m^2
600/0.04=15,000
====
The cost is 2.50 per tile.
RM 37,500
