Usually you can use one of the well-known formulae, for example the volume of a sphere, of a pyramid, etc.
To calculate the volume of an irregular object you will need a container with meaurements and water. Place the irregular object in your container and fill with water until the entire object is covered. Record volume A. Then remove the irregular object and record volume B. The volume of your irregulare object is equal to volume A minus volume B.
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.
by measuring the object
If the shape of the object is regular (a cube or a sphere) then the volume can be calculated from the measurement of the object's key dimension(s). And the object's mass can be determined in a mass balance. Give the mass and volume the density is calculated by dividing the mass by the volume. Where the object's shape is irregular, the volume may be determined by measuring the volume of a liquid displaced by submerging the object completely in that liquid.
Fill the object with water and pour it out into a graduated cylinder. This will give you the volume of any shaped container. If you want to find its displacement the opposite is needed. A tank of water. The water line is marked. The object is submerged and eureka you mark how high the water goes. Remove the object and measure how much water you have to add to the tank to reach the new line. That would be the displacement of your object. It is about the same as its' internal volume.
conclusion
cubed
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
LxWxH=Answer _ cm3
Depends on the shape. Basically, multiply the length times the width times the height, but there are many ways to do that.
Yes
height x length x width
The length times the width times the height.
Water Displacement Method?
It is length * breadth * height.
lenght x weight x height
Length times width times height.
