A beaker. Simply fill the beaker with a known quantity of liquid. Drop the object into the beaker, and measure the difference in the fluid levels.
the water displacement method
It depends on what the second method is!
uh, a pyramid.

equal the density of any other piece, assuming that the original cube was made of the same uniform substance.
Google "Archimedes' Principle" and see if that gives you a clue...
The volume of an irregularly shaped geometric object is typically determined by the amount of water it displaces when submerged. This method utilizes the principle of fluid displacement to calculate the volume of the object. By measuring the amount of water the object displaces, one can determine its volume.
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
Finding the center of gravity of an irregularly shaped object can be done using the plumb line method.
Measuring irregularly shaped objects by water displacement is a common technique because it provides an accurate volume measurement regardless of the object's shape. By comparing the volume of water displaced before and after placing the object in the water, you can determine the volume of the object without needing to calculate complex mathematical formulas.
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
To calculate the density of an irregularly shaped object, you would typically use a scale to measure its mass and a graduated cylinder to measure its volume by displacement of water. The density can then be calculated by dividing the mass by the volume.
the water displacement method
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.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
You can measure an irregularly shaped object by using a ruler, tape measure, or string to measure the object's length, width, and height, and then calculate its volume or surface area depending on the shape of the object. Alternatively, you can use a water displacement method by submerging the object in water and measuring the volume of water displaced to determine the object's volume.
