In general it is very difficult. The displacement method, often given as the answer does not always work.
The displacement method will work only if the object is reasonably small and you can find a liquid in which it is not soluble and in which it will sink.
For small objects, pour some liquid into a calibrated measuring jar and read off the volume. Then you submerge the object and read off the new volume. The difference between the two measures is the volume of the object.
For larger objects, it is easier to use two containers: for example a bucket placed in a basin. Completely fill the bucket. Very gently lower the object into the liquid in the bucket. Then carefully remove the bucket and measure the liquid that overflowed from the bucket into the basin. This will equal the volume of the object.
One way to find the volume of a large irregular shape object is to use the displacement method. Submerge the object in a container of water and measure the volume of water displaced. This volume is equal to the volume of the irregular object.
For an irregular shaped object that cannot be measured and then volume calculated with a formula.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
method usede to figure the volume of an irregular shaped object
There are several methods of measuring an irregular shape's volume.Filling it with a known volume of a substance until full.Summing up the Mathematical calculation of sections.
One way to measure the volume of an irregular shaped object is by using the water displacement method. Submerge the object in a known volume of water and measure the increase in water level, which is equal to the volume of the object.
If possible, fully immerse the object in water, and measure the volume of displaced water.
To find the density of a regular shaped object, you can calculate it by dividing the mass of the object by its volume. For irregular shaped objects, you would measure the mass of the object using a scale, then measure its displaced water volume when submerged in a graduated cylinder. The density can then be calculated by dividing the mass by the volume of water displaced.
Make a mold of the object and then fill the mold with water and measure the volume of the water.
The volume of the object.
To calculate the density of an irregular shaped floating object, you can measure its mass using a balance and then find its volume by submerging it in a known volume of water and measuring the water displaced. For a regular shaped floating object, you can simply divide its mass by its volume to find the density.
To find the volume of an irregular-shaped solid object, you can use a method called displacement. Fill a container with water, then submerge the object in the water and measure the amount of water displaced. The volume of the object is equal to the volume of water displaced, which can be calculated using the formula for volume of a regular shape.
