78 inches is 198.12 centimeters.
1 cms = 10 mms, hence 180 mms = 180/10 = 18 cms
There are zero CMs in a MM because CMs are larger than MMs. There are 10 MMs in one CM.
A inch is roughly 2.54cm and there are 12 inches in a foot, making a foot 30.48cm
152" = 386.08cm

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.
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*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.
55.5 inches is 140.97 cms.
