20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs

Oh, dude, it's like basic math time. So, there are 1000 millimeters in a meter, right? So, to convert 450mm to meters, you just divide by 1000. That gives you 0.45 meters. Easy peasy lemon squeezy!
1mm is 0.001 m

It depends on the shape of the 40m2. If it is 1m x 40m then, despite the area being 40m2, there is not a single 450mm x 450mm in it. The shape is simply not wide enough. But if you're allowed to cut up the slabs to make them fit, then you need 198 of them in order to cover 40 m2 of area.
45cm
450 mm = 45 cm
1 cm = 10 mm therefore the shelf is 450mm 450mm/9mm = 50 books
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
450mm x 300mm 45cm x30cm 1350cm
450mm*450mm = 0.2025 sq metres. Area to be covered = 1 square metre So number of flags required = 1/0.2025 = 4.9, or 5. However, 5 will leave the area looking like a mosaic.
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
450mm !
