equal the density of any other piece, assuming that the original cube was made of the same uniform substance.
the water displacement method
It depends on what the second method is!
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.
There are basically two techniques for finding the area of a shape with uneven or irregularly shaped sides. If the sides can be described by algebraic equations, then integral calculus can be used to find the area. Failing that, you can approximate the irregular shape by fitting in a number of smaller, regularly shaped polygons such as squares and triangles, whose area can be calculated by simple geometric techniques.
When an area or space is irregularly shaped it is often convenient to divide it into more than one area or space to make calculations. And example would be two pressure cylinders of different size connected together with a pipe and a valve. If the valve is opened you have created a larger volume.

Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.

The apple was irregularly shaped
A balance is used to measure the mass of an irregularly shaped solid.
Force it below the surface of water and measure the force required.
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
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)
The volume of an irregularly shaped solid can be measured by placing the solid in a known quantity of water in a container with measurement markings. Take the new volume and find the difference between this and the old volume. This is the volume of your irregularly shaped solid.
They're small, odd shaped, irregularly cut pieces of pasteboard or wood or the like that usually have a small part of a picture on them, that when fitted together form a design or picture.
Finding the center of gravity of an irregularly shaped object can be done using the plumb line method.
