You need to find volume by displacement instead of by formula when the object is not a regular solid. It could be an object like a pen where the height, weight, and length can't be easily measured, or a liquid.
You use the displacement formula when you put an object in water and need to find the volume of the object.
Displacement= Volume x Density for example to find the displacement of a ship you would do this formula: underwater volume(m3) x density(t/m3) so if you are a deck cadet like me this is the formula you would use to find the displacement of a ship in the first ship stability test! THIS IS WRONG! THERE ARE MANY DIFFERENT TYPES OF DISPLACEMENT FOR-INSTANCE THOSE USED IN PHYSICS ALL HAVE DIFFERENT FORMULE
You would find the density of a crown by dividing the crown's mass by its volume. The formula for density is density = mass/volume. Weigh the crown to find its mass and then measure its volume by displacement in a known liquid.
Displacement
There is no general formula. Many times an object can be looked at as the sum of smaller parts for which a formula is known. Ultimately all shapes can be reduced to small polyhedrons and then summed.

Displacement method.... Is the method to find volume of an irregular object
You can use displacement of water but you'll have to do it quickly before the sugar dissolves. You can also find a substance that sugar does not dissolve in and use that instead of water. If you change its state of matter, the volume might change.
Measure the amount of liquid that is displaced by the object in question (you will probably need a graduated cylinder). The amount of liquid displaced is the volume of the object. Then, since you have the volume of the object, you can find the mass of the object. Mass=Density x Volume.
