6 ft x 6 ft = 1828.8 mm * 1828.8 mm = 3,344,509.4 mm2 Area of each slab = 400*400 mm2 = 160,000 mm2 So minimum number of slabs = 3,344,509.4/160,000 = 20.9 ie 21 slabs. However, this requires almost all the offcuts to be used and, unless the shape is an exact number of tiles across, you will end up with an area that is a mosaic.
The answer will depend on the size of the patio 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.

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.

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.
First, convert the area of 12x24 feet to square meters: 12 feet is approximately 3.66 meters and 24 feet is about 7.32 meters, giving an area of about 26.8 square meters. The area of one 600m x 600m slab is 0.36 square meters. To find how many slabs are needed, divide the total area by the area of one slab: 26.8 ÷ 0.36 ≈ 74.4. Therefore, you would need 75 slabs to cover the area.
