23.41 sq m
279 sq ft = 25.92 sq metres so, at 0.36 sq metres apiece, 72 slabs. This assumes that all offcuts can be used - a totally unrealistic assumption in real life.
609,840 sq. ft.
Assuming the room is 18 FEET by 14 FEET, the answer is 252 sq ft
14 ft x 8 ft = 112 sq ft 112 sq ft /9=12.4444 sq yards
305.56
150 sq ft = 13.94 sq metres, approx. That area would require 68.8 or 69 slabs. However, this assumes that the area to be covered is "well-behaved" and that wastage is kept to a minimum.
23.41 sq m
18 * 12 = 216 sq ft; 216 / 450 = 0.48 or 1/2 slab.
Youll need 14.5 slabs - however add in 10% for breakage which frequently happens
279 sq ft = 25.92 sq metres so, at 0.36 sq metres apiece, 72 slabs. This assumes that all offcuts can be used - a totally unrealistic assumption in real life.
The answer depends on the units of measurement used for the numbers in the question: feet, metres, centimetres, miles, etc. Assuming they are measurements in millimetre, you will need 99 slabs. However, this assumes that the area is well behaved and also that you use most of the offcuts to fill up some of the space as a mosaic. If, for example, it is a path which is 0.230 mm wide then you may need 194 slabs.
609,840 sq. ft.
14 ft * 14 ft = 196 sq feet = 18.209 sq metres.
18 ft * 14 ft = 252 sq feet = 23.41 sq metres.
You will need a minimum of 153 slabs. However, that answer assumes that the area to be covered is "well behaved" and that you are happy to use offcuts and chippings so that part of the area will look like a mosaic. If these conditions are not met, you should consider getting 5% extra slabs.If, for example, the 55 sq metre area is in the form of a rectangle which is 550 mm wide and 100 metres long it may be easier to cover it using 167 trimmed slabs in a long line rather than use offcuts which are 5 mm wide.
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
