Density = mass/volume. You may have trouble finding density because the object may be irregular. To find volume of an irregular shaped object, you can apply calculus to calculate volume.~ Or you can use water displacement, You take a graduated cylinder and fill it full of water, record the amount, then place said object in the graduated cylinder and record the water level, subtract the original from the last and convert it to cc(hint hint: CC=ML) to get the volume, weigh it in order to get the mass and viola!

Weight it. Find it's volume. (hint - how much water does it displace). Divide.
Take an amount of water of which you know the volume. Drop the object in the water. Find the difference
Use volume displacement method.
It is used to find the volume of an irregularly shaped object. An object dropped into a volume of water will displace an equal volume of water.
When you are trying to find the volume of an irregularly shaped object.
It is the displacement method.
It depends on the way the question is asked. If you are dealing with a cubic or rectangular object, you measure the length, width, and height, and multiply them. If it is a spherical or irregularly shaped object, you could used water displacement to find its volume. If it's a liquid, you could use a graduated cylinder to measure its volume.
Use the triple beam balance to find
This depends upon the phase of the material whose density you wish to find. Fir an irregularly shaped solid, you would have to find the volume using a graduated cylinder (to measure how much liquid it displaces) and then weigh it on a scale (probably a triple beam balance). A regularly shaped solid would not require a graduated cylinder, you could just get its measurements with a ruler. A liquid could be measured using a graduated cylinder and a scale. A gas could have its density relative to that of the air measured by observing its buoyancy vs. weight measured in a balloon. That is a bit more complicated.
Using a graduated beaker, add water sufficent to totally immerse the object. Note the initial volume of the water without the object.
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.
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.
