It depends on how accurately you do the measurements in each case.
Water displacement
direct measurement and displacement
Water displacement is a method to measure 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.

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.
Volume is difficult to calculate mathematically in a complex shape. Immersing an object in a liquid pushes out a volume of that liquid equal to the volume of the object. The result is called displacement because the solid displaces the liquid.
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.
haha we are both looking for the same question because its on one of my quizzes hehe
Yes. It doesnt have to be a irregular even though sometimes it is easier just to do the math... for a rectangular object. l x w x h= volume
