90cm is the longest because 400mm = 40cm and 0.5m = 50cm
400mm x 400mm x 400mm = 64,000,000mm3 = 0.064m3
4dm=400cm that's what i think but I'm not so sure.
They're the same amount because 10cm= 1dm and 10x4=40 and 1x4=4 and 4dm= 40cm
A dm (decimetre) is equal to 10cm (centimetres). So the answer to the question is 4dm is exactly the same length as 40cm.
It is 0.7 or 7/10.
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
Neither - they are the same measurement.
can use 400mm THW,RHW,RUH (rating: 400mm = 388amperes)
