Since an inch has exactly 2.54 centimeters, a square inch has (2.54 x 2.54) square centimeters.
So (2.54 cm / in)2 = 6.4516 cm2 / in2, then multiply by 4 in2 = 25.8064 cm2
12cm*20cm = 240 cm2 = 37.2 sq inches = 0.258 sq ft
1 in = 2.54 cm (exactly) 1 sq in = 1 in x 1 in = 2.54 cm x 2.54 cm = 6.4516 sq cm ⇒ 4 sq in = 4 x 6.4516 sq cm = 25.8064 sq cm ≈ 25.81 sq cm
To convert from square inches to sq cms, multiply by 6.452.
45 sq metres / 50 sq cm = 450000 sq cm / 50 sq cm = 9000 tiles.
