Calculus will work, if you have an equation describing the precise shape of the object.
If you don't (and probably even if you do), it's far easier to actually measure it (by submerging it in water and measuring the amount of water displaced) than it is to calculate it.
conclusion
It is length * breadth * height.
Water Displacement Method?
The length times the width times the height.
length x width x height. So if you had an object that was 10cm long, 10cm wide and 10 heigh the volume would be 1000 cm3

Water Displacement Method?
It is length * breadth * height.
Usually you can use one of the well-known formulae, for example the volume of a sphere, of a pyramid, etc.
First you get the object mass by weighing it.Then you get its volume by immersing it in a scaled water container and see the increase in water volume which gives the object volume.Then you divide the mass by the volume to get the object density.
length x width x height. So if you had an object that was 10cm long, 10cm wide and 10 heigh the volume would be 1000 cm3
method usede to figure the volume of an irregular shaped object
by measuring the object
It all depends upon the shape of the object. For example, the volume of a rectangular prism is lengthxwidthxheight. For an irregular shaped object, one strategy is to immerse the object into a measured amount of water, then measure what is the total volume of water plus object, and subtract the original volume of water.
To calculate the volume of an irregularly shaped object, a good idea would be to get a bucket full of water and submerge that object into the bucket. Then measure the amount of water that runs over and that should be the volume of your object. For example if you take a sealed bottle of bottle stick it in a bucket filled with water, then let it's volume filll the space and displace the water. The water that is displaced or the water that runs out is the volume of your irregular shape. Get it?
The volume of the object.
