400mm = 0.4m 90cm = 0.9m 0.5m = 0.5m 0.9m > 0.5m > 0.4m, so 90cm is the longest.
600mm * 400mm = 0.6m * 0.4m = 0.24 sq metres
In the Philippines, concrete louver blocks typically come in standard sizes, with common dimensions being 400mm x 400mm (16 inches x 16 inches) or 600mm x 600mm (24 inches x 24 inches). The thickness usually ranges from 50mm to 100mm. These blocks are designed for ventilation and aesthetic purposes in various construction applications. However, specific sizes may vary by manufacturer, so it's advisable to check with local suppliers for precise measurements.
Well a mm is half a cm so i think they are the same equivalent.
90cm is the longest because 400mm = 40cm and 0.5m = 50cm
To determine how many 400mm x 400mm slabs are needed to cover an area of 6ft x 8ft, first convert the dimensions to millimeters: 6ft is approximately 1829mm and 8ft is about 2438mm. The area to be covered is 1829mm x 2438mm = 4,467,642mm². Each slab covers an area of 400mm x 400mm = 160,000mm². Dividing the total area by the area of one slab gives approximately 28 slabs needed (4,467,642mm² ÷ 160,000mm² ≈ 27.92).
40cm is 400mm
