You cannot measure the mass of a solid with a graduated cylinder.

You use a graduated cylinder to measure the volume of the rock with the water and the water without the rock
A graduated cylinder is not inherently harmful, but misuse can lead to injury. Dropping or mishandling a graduated cylinder can result in broken glass shards that may cause cuts. Additionally, using the cylinder to handle hazardous chemicals without proper precautions can be harmful.
Use a borosilicate glass graduated cylinder when applying heat, as it can withstand higher temperatures without breaking or shattering. Avoid using plastic graduated cylinders as they may melt when exposed to heat.
Density is Mass/Volume. Without a measure of volume you cannot calculate density.
Water does NOT have a volume of 1230 cm. It has a volume of 1230 cm^3 or 1230 mL 'cm' is a linear measure NOT a volume measure. Density = 122 g/cm^3 NOT 1.22 g , this is the weight of a mass. Remember density = mass/ volume. Algebraically rearrange mass = density X volume Hence Mass(g) = 1.22 g/cm^2 X 1230 cm^3 mass = 1500.6 g or 1.5006 kg. NB Please make sure you write the correct units!!!!!
Tilting the graduated cylinder allows the object to slide down gently without splashing or bouncing. This helps to prevent the formation of air bubbles that could affect volume measurements.
The density of a liquid can be measured with a beaker. the beaker is weighed alone, then a specific measured volume of the liquid is placed in the beaker and the beaker is reweighed. The difference between the beaker with and without the water is noted. from there the mass of the liquid for the specific volume is then known. using hte formula d = m/v, we can therefore determine the density. where m is in kg and v is in liters.
Use a Graduated Neutral Density Filter.
What do you want to measure - mass, weight, volume, density. There's no answer for "measure" without indicating what is to be measured.
Place the 12 sided figure into the graduated cylinder, then fill the cylinder with water. Take note of how high the water level is (W1) . Fish out the 12 sided figure without removing much of the water. Take note of how high the water level is now (W2). The volume of the 12 sided object equals the difference in water level (W1 - W2).
As a chemist I can tell you that there are a significant purpose differences between the two, though sometime masked in high school chemistry. In college you learn that the graduated cylinder are more specifically designed to measure volume of a liquid. The test tube is glass which is safer to do most chemical reactions in - meaning the test tube is not generally used for measurement but rather a container for liquids.
