17.71653 inches.
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
To determine how many 450mm x 450mm slabs are needed to cover a 5ft x 4ft area, first convert the dimensions to millimeters: 5ft is approximately 1524mm and 4ft is approximately 1219mm. The area of the space is 1524mm x 1219mm = 1,860,756 mm². Each slab covers an area of 450mm x 450mm = 202,500 mm². Dividing the total area by the area of one slab gives you approximately 9.2, so you will need 10 slabs to cover the area completely.
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!
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.
450mm x 300mm 45cm x30cm 1350cm
45cm
450mm !
You need only 8 and half sheets of slab.
450 mm = 45 cm
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
1 cm = 10 mm therefore the shelf is 450mm 450mm/9mm = 50 books
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
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.
