To calculate how many 400mm x 400mm paving slabs fit in one square meter, first convert the dimensions of the slab to meters: 0.4m x 0.4m. The area of one slab is 0.16 square meters (0.4m x 0.4m). Therefore, to find how many slabs fit in one square meter, divide 1 square meter by the area of one slab: 1 / 0.16 = 6.25. Since you can’t have a fraction of a slab, you can fit 6 slabs in one square meter, with some leftover space.

20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
You will need 63 44cm x 44cm slabs to cover that area.
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.
220 should do it.
