density=mass/volume
therefore,.. d=20g/12
=3g/5 is the density
hope it will help u guys.....
Eraser is made out of rubber.Erase pencil or dry erase marker. Depends.
Use some tape and wrap it around the eraser then take it off.If that doesn't help use a pencil eraser and erase the eraser.That will make it cleaner and soft.
Who invented the pink pears Eraser? I think it was Joseph Priestley but I'm not sure.
Yes, but only if the shavings could be ground into a fine powder
Put the eraser in the freezer for at least 48 hours then take out and let sit for 5 min, put eraser in microwave (make sure to watch at all times) wait until eraser is soft pull out and mold or you can erase the eraser on a wood table and these strings will start forming. collect the strings and get a eraser ball! let it harden and then eraser!
An eraser sinks because it is denser than water. The density of an object determines whether it will float or sink in water. In the case of an eraser, its density is greater than that of water, so it sinks.
To determine the density of a rubber eraser, you would first measure the mass of the eraser using a scale. Next, measure the volume of the eraser by submerging it in a graduated cylinder filled with water and recording the water displacement. Finally, divide the mass of the eraser by its volume to calculate the density.
The density of an eraser is typically measured in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). These measurements indicate the mass of the eraser per unit volume.
An eraser typically sinks in water due to its density being higher than that of water.
The density of an eraser can vary depending on the material it is made from, but typically falls in the range of 1 to 1.5 grams per cubic centimeter. This means that an eraser is relatively light compared to many other objects of similar size.
The relative density of a rubber eraser is typically around 1.1 to 1.3, which means it is slightly denser than water. This allows the eraser to effectively remove pencil marks from paper without leaving residue or tearing the paper.

erase something and get the shavings from the eraser and melt them together and you are done

The plural of eraser is erasers.
Friction causes the eraser to become warm.
