1cm = 10 mm
7cm = 7 x 10 mm = 70mm
There are 10 mm in 1 cm, so 6 cm = 60 mm, then add the 7 mm for 67 mm.
multiply by 10= 700 mm
70mm
1 cm = 10 mm 38.2 cm = 382 mm
1 cm = 10 mm 2 cm = 20 mm . . 10 cm = 100 mm . . 15 cm = 150 mm
1 cm = 10 mm So 7/10th of a cm is 7 mm
70mm (cm x 10 = mm)
One cm contains 10 mm. So, 7 x 10 = 70 mm.
There are 10 mm in 1 cm, so 6 cm = 60 mm, then add the 7 mm for 67 mm.
multiply by 10= 700 mm
70mm
There are: 7 cm = 70 mm
7 inches = 177.8 millimeters
3.5 cm is 5 times as long as 7 mm, and 4 times longer than 7 mm.
1 inch makes 2.54 cm Therefore, 7 inches would make 7 x 2.54 cm, which is 17.78 cm. 1 cm makes 10 mm Therefore, 17.78 cm would make 17.78 x 10 mm, which is 177.8 mm. Therefore, 7 inches are 177.8 mm.
1 inch is equal to 2.54 cm i.e 25.4 mm So 7 inches is equal to 17.78 cm i.e 177.8 mm.
7 cm is much smaller than 698 mm 698 mm = 69.8 cm whereas 7 cm = 70mm
