    I think that your prism is like below: |dw:1439805080062:dw|

    namely, your prism is truncated by means of a plane which is not parallel to the plane which contains the base of your prism

    It is not simple, in order to get your answer we can use the integral calculus in three dimensions

    otherwise, you can draw your prism, using AutoCAD, and then there there is a command which allows to get the volume of such prism

    yes! we have to consider the equations of some planes
