45,000 millimeters is 147.64 feet (147 feet and 7.65 inches.).
45cm
450 mm = 45 cm
To determine how many 450mm flags can fit in a 20ft x 20ft area, first convert the dimensions to millimeters: 20ft is approximately 6096mm, so the area is 6096mm x 6096mm. The area of one 450mm flag is 450mm x 450mm, which equals 202,500mm². Dividing the total area (37,184,256,000mm²) by the area of one flag gives approximately 183,000 flags that can fit in that space, assuming no gaps between flags.
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.
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 x 300mm 45cm x30cm 1350cm
To determine how many 450mm slabs you need for a 6 ft x 4 ft base, first convert the dimensions to millimeters: 6 ft is approximately 1829mm and 4 ft is about 1219mm. The area of the base is 1829mm x 1219mm = 2,233,851 mm². Each 450mm slab has an area of 450mm x 450mm = 202,500 mm². Dividing the total area of the base by the area of one slab gives you approximately 11 slabs needed (2,233,851 mm² ÷ 202,500 mm² ≈ 11).
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
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.
