This is actually how people approximate real volume of obscured 3D objects.
Integration can be used to calculate the area under a curve and the volume of solids of revolution.
Its importance is tremendous - it has many different applications. Some of the applications include calculation of area, of volume, moment of inertia, of work, and many more.
volume integral
A derivative is to the rate of change asan integral is to area/volume.
Geometrically the definite integral from a to b is the area under the curve and the double integral is the volume under the surface. So just taking the integral of a function does not yield the volume of the solid made by rotating it around an axis. An integral is only a solid of revolution if you take an infinite sum of infinitesimally small cylinders that is the disk method or you do the same with shells.

While I searching for the answer to this question, I totally confused. Atlast I reach in one thing that we may compute some volume integrals by using double integral but to evaluate a triple integral we should go through all the three integrals.
Because its applications are part of the integral elements in our society..

What are the Applications of definite integrals in the real life?
A triple integral will usually give a measure of volume in 4-dimensional hyper-space.
A line integral can evaluate scalar and vector field functions along a curve/path. When applied on vector field, line integral is considered as measure of the total effect of the vector field along a specific curve whereas in scalar field application, the line integral is interpreted as the area under the field carved out by a particular curve.Line integral has many applications in physics. In mechanics, line integral is used to determine work done by a force in moving an object along a curve. In circuit analysis, it is used for calculating voltage.
A triple integral should suffice to locate the volume. Provided you can determine a equation to bound the surface.
