A typical 30cm plastic ruler weighs around 30-40 grams, while a wooden ruler of the same size may weigh slightly more.

A standard ruler is typically 30cm long, so an object that is 19.5cm long could be a smaller ruler, a pencil, or a regular sized envelope.
The weight of a foot ruler is probably about 1 pound a little under a pound, but it is extremely light.
The weight of a ruler in newtons would depend on its mass and the acceleration due to gravity. Typically, a standard ruler would have a very small mass, so its weight in newtons would be very minimal, likely less than 1 newton.
A ruler floats in water because its density is lower than that of water. This means that the weight of the water it displaces is greater than its own weight, allowing it to float.

a 30cm ruler
To measure 720mm with a 30cm ruler, first note that 720mm equals 72cm. Since the ruler only measures up to 30cm, you would need to use it multiple times. Measure 30cm twice to get 60cm, then measure an additional 12cm using the ruler, which can be achieved by marking the 12cm point on the ruler after measuring the full 30cm twice. This will give you a total of 72cm or 720mm.
30cm is about 12 inches or 1 foot in length
To measure a 750mm long ribbon using a 30cm ruler, first convert 750mm to centimeters, which is 75cm. Lay the ruler down alongside the ribbon and mark the end of the 30cm measurement. Move the ruler to the end of the marked point and measure another 30cm, marking again. Finally, measure the remaining 15cm to reach a total length of 75cm (or 750mm).

A 30cm Ruler.
Look at a ruler, if you don't know....
Anything that measures length: a 30cm ruler, a metre ruler, a tape measure etc.
Depending on the size of it id say either a 15cm ruler or a 30cm ruler.

On a 30cm ruler you can't get it exactly, you need a higher tech ruler which has the markings of 2.54cm. If you have a normal ruler you have to estimate.
