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
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 answer will depend on what "it" is.
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.
It's volume.
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 trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
It is a volume (3D) shape - "solid" has nothing to do with it.
There is no such thing as a 3D triangle.
You find the length and height of the shape, them you find the volume
find the volume of the shape first and then take away the volume of the holes
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).
You use disfigurasation
The answer is zero. A 2D shape has no volume.
