Since 1 cm = 10 mm 8cm = 80mm So, 80mm/5mm = 20 Therefore, 8cm is 20 times longer than 5 mm.

7cm because if the mm was 5 or over then it would be closer to 8cm but it is lower than 5 so it is closer to 7cm.
In order to solve this you first need to convert the cm value into mm. This is to give a number that's easy to work with, and has consistent units with the rest of the question. There are 10mm in a cm. Thus to convert from cm to mm, you need to multiply by 10. In this case we have 8cm. This converts to mm as 8x10 = 80mm. So the question is 80mm + 6mm. This works out at 86mm.
81mm is more ie 81mm=8.1cm
Since 1 cm = 10 mm 8cm = 80mm So, 80mm/5mm = 20 Therefore, 8cm is 20 times longer than 5 mm.
80mm
80
8cm is the same as 80mm

1 cm is = to 10 mm so 8 cm is = to 80 mm
7cm because if the mm was 5 or over then it would be closer to 8cm but it is lower than 5 so it is closer to 7cm.
By unit of length and distance and conversion ,we can say that 1 cm=10 mm converting 8 cm to mm is 80 mm now,finding ratio 80 :5 16:1
There are 0.8 centimeters that equal to 8 millimeters.

There are 10mm in a centimetre. This means you have to multiply cm by 10 to get mm. i.e. 8*10 gives you 80 millimetres.
5 mm x 5 mm = 25 mm2
