Because the L, for example, will not be the same at all points along the irregular object's W or H. And similarly with the other two measures.

break it up into pieces you know how to find the volume of
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.
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 volume of an irregularly shaped object, a good idea would be to get a bucket full of water and submerge that object into the bucket. Then measure the amount of water that runs over and that should be the volume of your object. For example if you take a sealed bottle of bottle stick it in a bucket filled with water, then let it's volume filll the space and displace the water. The water that is displaced or the water that runs out is the volume of your irregular shape. Get it?
yes you can use a balance to measure the volume of an irregular shaped solid.
Use volume displacement method.
When you are trying to find the volume of an irregularly shaped object.
Volume displacement.
the water 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.
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. The difference between the before and after levels of the liquid is the volume of an immersed object.
