The volume of any rectangular solid, including a cube, is calculated mathematically as V = l × w × h
In a given calculation, if you are given the:
To find this, you would have to use the area of its base which is:
Length * Width * Height.
Furthermore, if the cross-section is parallel, then you would have to solve it thus:
Length * Width which is the area of the section from top to bottom.
