Use the Archimedes' method, fill a container with water (right to the top) with a spill tray underneath to catch the water over flow, drop the rock in and measure the amount of water displaced. This method will be about as accurate as you can get.
To calculate the density of an irregular object like a rock, you can measure its mass using a scale and then determine its volume using the water displacement method. Once you have the mass and volume, you can divide the mass by the volume to obtain the density of the rock.
You can find the volume of an irregularly shaped object, like a rock, by using the water displacement method. Submerge the object in a known volume of water in a container. Measure the increase in water level, which equals the volume of the rock.
Personally, what I would do would be to experimentally find a lead fishing sinker, rock, gold coin etc., which, when added to the irregular object, sinks them both. For accuracy, the object selected should be smaller than the irregular object. The smaller, the better. Then, in the usual way, find the volume of the sinker, the rock, or the gold coin alone. Write it down so I don't forget it. Finally, glue the 'ballast' to the irregular object, and measure the volume of the combination by sinking it. From the volume I find, subtract the volume of the ballast alone, and I'll have the volume of the irregular object.

Not always easy. Since density is defined as the mass of a unit volume of material,you would measure the volume of the rock by putting it into a container half filled with water and then measure the volume change.
He discovered the method to calculate the volume of a irregular object (rock).
To find the volume of an irregular object such as a rock, you have to use displacement. If you place the object in a graduated cylinder filled with water, the volume of the object is equal to the amount of water that the object displaces. For example, if a graduated cylinder is filled with 100mL of water, and you place an object such as a rock and the water rises from 100mL to 106mL, then the volume of the rock is 6.

The volume of a solid object such as a rock or pebble can be determined by submerging it in a liquid in a graduated cylinder or other container. The difference in the volume of the liquid is the volume of the object.

You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
The best way to find the volume of an irregular solid is to submerge it in a liquid and see how much the liquid rises. You can also use calculus and tripple integrals, but that gets really sticky.

First, measure the volume of water displaced when the rock is submerged in a known volume of water. Then, divide the mass of the rock by the volume of water displaced to calculate the density.
Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's irregular volume. However, by measuring the volume of liquid a rock displaces, its volume can easily be determined.
