Well it depends on what kind of 3d shape it is. There is a formula to find the volume of each 3d shape. The main formula for volume is Bxh. (Big B multiplied by the height.) Bxh means the area of the base times the height.
Volume
The answer will depend on what "it" is.
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
The 3D space inside a shape is it's volume.
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.

A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
Only if the shape is a cuboid.
It is a volume (3D) shape - "solid" has nothing to do with it.
There is no such thing as a 3D triangle.
To find the volume of the 3D shape made up of identical 1 cm^3 cubes, you would need to count the total number of cubes and multiply it by the volume of one cube. For example, if there are 100 cubes, the volume would be 100 cm^3.
