First you convert 0.3m into 30cm because 0.3cm is out of 10dm then you start at the end of the ribbon and measure up to 30cm and mark that with your finger and there you go cut where you marked it and there is 30cm r if you have a better answer please help i dont know if this is good I'm only 10 Grade 5
Quite easily - 30cm is exactly the same measurement as 0.3 metres !
By unit of length and distance and conversion ,we can say that a centimeter ruler used for measuring the length,width of the objects in centimeters ,etc.
If you mean tools then: -Ruler -Tape Measurer Etc If you mean unit then: -Centimeter/Milimeter/Meter -Inch/Foot
A metric ruler is use to measure centimeter and millimeters.1 centimeter (cm) = 10 millimeters (mm) .
the measuring ruler that we use are the object which has length of 15 cm. 1 ruler =15 cm.
Get a centimeter ruler and then convert it to what measurement you want.
Well is what i would do is get a ruler and measure it out on a ruler and it can probs be stopped anyway
1 cm = 10 mm. Start with ruler at 0 and mark ribbon at 30 cm. Then place ruler at the mark and measure 30 cm more and make another mark- you are up to 60 cm or 600 mm. Then place ruler at this mark and measure 5 cm, or 50 mm. Now you have a 650 mm ribbon.
Ruler. you measure with a ruler, yard stick, tape measure, or estimate.
A ruler!
Yes, the ruler does need to be straight when finding or measuring the length of a country on a map. If the distance curved, you can use a string and the ruler to measure the length.
You don't measure with length. You measure the length of an object with a ruler. You would use inches or metres as your units.
a metric ruler, meter-stick, centimeter ruler, and inch ruler are all used to measure length or distance
