Weight it.
Find it's volume. (hint - how much water does it displace).
Divide.
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.
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.
To find the volume of an irregularly shaped object that would dissolve in water, you can use the water displacement method. Fill a known volume of water in a container, note the initial water level, then submerge the object in the water and measure the new water level. The difference in water levels is the volume of the object.
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a graduated cylinder. The density can then be calculated by dividing the mass by the volume of water displaced.
Unknown: Volume of chunk of copperKnown:density = 8.94g/cm3 (Wikipedia)mass of irregularly shaped chunk of copper = 1.5kg = 1500gEquation:density = mass/volumeSolution:volume = mass/density = 1500g/8.94g/cm3 = 167.8cm3 = 170cm3 (rounded to two significant figures)

equal the density of any other piece, assuming that the original cube was made of the same uniform substance.
Half fill a graduated glass beaker with water and note the level. Place irregularly shaped object into the beaker. Note the new level. The difference between the two levels is the volume of the object. cw: OK, that method works for objects that don't get wet -- like steel. Tissue paper would not be a good candidate. Also, if the object floats, you have to submerge the object.

You would typically use the "lasso tool" or "pen tool" in graphic design software like Adobe Photoshop to select an irregularly shaped object with both curves and straight lines. The lasso tool allows for freehand selection, while the pen tool offers more precise control for outlining complex shapes.
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.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
You compare its mass with something of known mass. In everyday earthbound conditions, this would mean weighing it on a set of weighing scales or on a spring balance.
