The rectangular floor is 6 meters long and 3 meters wide, so its area is:

Area = Length × Width = 6 m × 3 m = 18 square meters

Since each square tile has an area of (20 cm) × (20 cm) = 400 square centimeters, we need to convert the area of the floor to square centimeters:

1 square meter = 10,000 square centimeters (since 1 meter = 100 centimeters)

So, the area of the floor in square centimeters is:

18 square meters × 10,000 square centimeters/square meter = 180,000 square centimeters

Now, to find the number of tiles needed, we divide the total floor area by the area of each tile:

Number of tiles = Total floor area / Area of each tile

Number of tiles = 180,000 square centimeters / 400 square centimeters

Number of tiles = 450 tiles

Therefore, the correct answer is 450 tiles are needed to cover the floor.
