4.9382716 to be precise, so 5, 450x450 slabs in a square metre.
Answer: 340' x 450' (153,000 square feet) = 3.51239 acres.
To determine how many slabs of size 450 mm x 450 mm are needed for an area of 10 m², first convert the slab dimensions to square meters. Each slab is 0.45 m x 0.45 m, which equals 0.2025 m² per slab. Therefore, to cover 10 m², you would need 10 m² ÷ 0.2025 m²/slab ≈ 49.38 slabs. Since you can't have a fraction of a slab, you would need 50 slabs.
first lets convert m to mm.we know, 1 m=1000 mm. 5 m =5000 mm and 8m=8000mm. Now, no.of paving slab = area of flags /area of slab . =5000 X8000/450 x 450. =197.5 = 197 slabs.
40 acres. Mutiply 1320 x 1320, then divide by 43560 (number of sq ft in one acre)
