Yes.
Given a cuboid it is always possible to have a cylinder with the same volume.
Yes, that is possible.
There cannot be any such object as a cylinder cuboid.
A cuboid cylinder is an impossible shape - just as a square circle is.
If the dimensions of a cuboid are a, b and c, then its volume is a * b * c
no
A cylinder has a circular cross-section whereas a cuboid has a quadrilateral cross-section.
Volume of a cuboid = cross-section area times its length
If the area of the base and the height of the cylinder and the cone are the same, then the volume of the cone will always be one third of the volume of the cylinder.
The volume of a cone is 1/3 of the volume of a cylinder with the same radius and height
The cone has 1/3 of the volume of the cylinder.
Same as a cylinder
