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

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
182.9 cms
450mm x 300mm 45cm x30cm 1350cm
5' 9" = 175.26 cms
10 cms in one mm
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.
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
