Determine the mass of the given body using a physical balance. Let it be 'M'.

Take some water in a measuring jar( water in the jar should be sufficient to immerse the solid). Note the initial level of water, let it be 'A'. Suspend the solid inside the jar using a thread so that the solid is fully immersed in the water, without touching the sides or bottom of the measuring jar. Note the water level. Let it be 'B'.

Then volume of the solid = A - B.

Then density of the solid = M/V.

First 'weigh" the ojbect on a scale. this gives the mass. 2nd use the water displacement method to find the volume. Then divide Density = mass / volume.

If the solid is a regular shape, such as a cylinder or sphere, you can find the appropriate dimensions and use formulas to find the result. If it is of a irregular size, I doubt if there is another method (even if there is, displacement of water would most likely be the simplest method)

It is a method called displacement. Displacement is a method that many scientists use. First you put a certain amount of water in a container (test tube, beaker). Second you Measure how many milliliters of water you put into it. Next you Add your irregular object into the water. Then you measure how many milliliters the water level rose. Then you subtract your second measurement with the irregular shaped object in it by your first measurement without the object in it and it will give you the volume of your irregular shape object.

An irregular shape!

How to calculate the volume for an irregular shape? Well, this is easy. First let me tell you the materials you need for this experiment.1. Displacement can2. Tripod Stand3. A Beaker4. A measuring cylinder5. A thread6. Water7. You irregular objectSteps:Place your displacement can on your tripod standPlace your beaker right below the spout of your displacement canfill the displacement can to its brimlet the water flow out of the spout into the beakerwhen it has stopped, replace your beaker with a measuring cylindertie your irregular object to your piece of thread, make sure it is tightslowly lower your irregular object into the displacement canyou will see water flowing out of the spout while you do thatafter your irregular object is at the bottom of the displacement can, read your measuring cylinder at eye levelExtraIf you see an round curve when you are reading the measurementread the lower line at eye levelYou have found the volume of your irregular object! Congratulations.

"displacement volume"

if it is a solid, use the water displacement method.

There are many ways to find the volume of irregular shapes, but the most commonly used method is Water Displacement.

Measure the displacement of water when the object is submerged in water. This gives the volume ; then weigh the object and divide the weight by the volume to get the density.

Displacement

You do not need fancy lab equipment.Basically you need to determine two pieces of information1) The mass of the "irregular" shape (use a scale)2) The volume of the shape (use water displacement in a bucket/tub to find volume)Take the mass / volume and you have density.

Because some objects have an irregular shape, therefore cannot be measured like a square could.
