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

first lets convert m to mm.we know, 1 m=1000 mm. 5 m =5000 mm and 8m=8000mm. Now, no.of paving slab = area of flags /area of slab . =5000 X8000/450 x 450. =197.5 = 197 slabs.
20ft x 10ft x 7ft = 1400 cubic feet 1 yard of dirt = 27 cubic feet Hence yards required = 1400/27 = 51.85
Depends on the size of the flags.
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
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*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.
450mm x 300mm 45cm x30cm 1350cm
You need only 8 and half sheets of slab.

20ft x 28ft = 560ft2

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.
