It depends on how accurately you do the measurements in each case.
Water displacement
direct measurement and displacement
In indirect measurement of volume, displacement involves measuring the volume of a solid object by submerging it in a liquid and measuring the volume of liquid displaced. The difference in volume of the liquid before and after submerging the object corresponds to the volume of the object itself, allowing for an indirect measurement of the object's volume.
The Liquid Displacement Method involves putting an object into a container filled with water. A measurement is then taken of how much volume of water has been displaced. This measurement can then be used to calculate the volume of the object displacing the water.

Displacement of water is an indirect measurement because we cannot directly measure the volume of an irregularly shaped object. By measuring the water displaced when the object is submerged, we can indirectly determine the volume of the object based on the volume of water displaced, according to Archimedes' principle.
It is length*width*height - in suitable measurement units.
The measurement of length, width, and height finds the volume of a cube or rectangular prism.
To find the density of a rectangular solid object, you would calculate the mass of the object by multiplying its volume by its density. For an irregular solid object, you would typically measure its mass using a balance and its volume using displacement of water, then divide the mass by the volume to find the density. The main difference lies in how you determine the volume of the object, with rectangular solids having a straightforward formula for volume calculation compared to irregular shapes which require more complex methods.
A cube is a rectangular prism with all sides of the same length. So, volume of a rectangular prism is Length*Breadth*Height = L*B*H But for a cube, L = B = H so volume = L*L*L = L3
The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.
In finding the density of a rectangular solid object, you can simply calculate it by dividing the mass by the volume using the formula density = mass/volume. However, for an irregular solid object, you may need to use techniques like displacement method or water displacement method to determine its volume before calculating the density.
