3.4 metres=340 cm=3400 mm
5 M or 5 metres is the larger of the three.
5 cm = 50 mm which is greater
420 mm is greater than 4.2 cm
680 mm is the same as 68 cm
340 cm would be greater than 3200 mm as 340 cm is equivalent to 3400 mm (340 x 10). So, from there, do the math. 3400 > 3200.
340
3.4 metres=340 cm=3400 mm
5 M or 5 metres is the larger of the three.
64 cm is greater than 630 mm which equals 63 cm
5 cm = 50 mm which is greater
Cm are greater
3.4 cm equals 34 mm which is greater than 30 mm
6 cm is greater than 50 mm which equals 5 cm
201 mm = 20.1 cm So, no, it isn't greater.
420 mm is greater than 4.2 cm
680 mm is the same as 68 cm
