20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
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.
For blocks that are 450mm x 225mm , you will need 9.88 blocks per square metre.
The volume of a cylinder (V) = πr2h, where π=pi, r=radius of the base, and h=height.Assuming the cylinder has an OUTSIDE diameter of 450mm, the INSIDE diameter is 400mm and the radius (r) is 200mm, or 0.2m. Plug in the values of your cylinder:V= 3.1415927 * 0.2m * 0.2m * 6.5m = 0.816814m3, or about816.81 Liters

You need only 8 and half sheets of slab.
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*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
350mm to 450mm depends on the regions. Sask is huge
SRA3 is an ISO paper sheet size which is 320mm x 450mm in dimensions.
