45cm
450 mm = 45 cm
The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions. 21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs. To complete the rectangular area, 14.2 x 12.9 = 183 slabs.
You need only 8 and half sheets of slab.
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

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!
