volume of a rectangular prism = length * width * height
The volume of anything is always the area of the base of the object times the height. Therefore, to find the volume the object must have a height, which makes volume work with all 3D shapes. If one is looking at a 2D shape, then there is no height so a volume cannot be calculated (note: areas may be found of 2D shapes).

There is no such thing as a 3D triangle.

A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
area is 2D and volume is 3D. think of volume as the amount of space inside a 3D object like a ball.

It's volume.

No. If it's 3D it's volume. Area is 2D
