How to calculate the volume between the sections?

Question

when we want to caمculate the volume of the mass of a mountain or any other masses look like IMPERFECT or HALFCone, while you the sections of the mass and the distance between them, what should we do?

Answer 1

You need to phrase that a lot more clearly, I fear.

Also, it depends on:

1. What the shapes are.
2. Whether or not you know calculus of several variables.

One trick that sometimes helps is to compute the volume of a larger shape, and also the volume of a shape that is left out, and subtract the second from the first to get the volume of what's left over.
