400 mm = 1.31 feet, approx.
1125
5.15 feets
three feets
the answer to that is 4cm
10x10=100 ft
1 yard are 3 feets
157 centimeters is 5.15 feet.
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).
400mm equals 15.74 inches. Direct Conversion Formula400 mm* 1 in 25.4 mm = 15.7480315 in
50 feet (not feets) equal 15.24 metres (not maters).
