A standard ruler's actual size is 12 inches long. Rulers may be plastic, metal or wooden. Often rulers have metric measurements on one side even though the metric system is not used in the United States, at least not for official purposes.

They are equal
why are the division lines on a ruler diffrent lengths
use your ruler to measure the sides
Not necessarily. I have one which is plastic.
Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.
That will depend on the size of the ruler and what it is made out of. A plastic or wooden ruler will be very light, maybe an ounce. A steel ruler will weigh much more.

Depends on the length AND material of both. The generic comparison between a 15cm wooden pencil, with a 30cm plastic ruler: most likely the ruler weighs more.
A typical 30cm plastic ruler weighs around 30-40 grams, while a wooden ruler of the same size may weigh slightly more.
A typical plastic ruler weighs around 0.3 to 0.5 ounces, while a wooden ruler may weigh slightly more, around 0.5 to 1 ounce.
The weight of a ruler can vary depending on the material it is made of. On average, a plastic ruler weighs about 5-10 grams, while a wooden ruler may weigh between 10-20 grams.
A metric ruler is divided into centimeters, with each centimeter further divided into 10 smaller units called millimeters. This allows for precise measurements in the metric system.
A ruler or a metric tape measure is commonly used to measure length in the metric system. These instruments typically have units of centimeters or millimeters for more precise measurements.
A ruler with smaller, more closely spaced markings will provide a more precise measurement of the distance traveled by the snail. A metric ruler with millimeter markings would be the best option to achieve precise measurements.
A pull push ruler is used for measuring linear distances. It typically has a spring-loaded mechanism that allows the ruler to extend and retract easily. It is commonly used in carpentry, woodworking, and other trades where precise measurements are needed.
