Put the object in a bath of water and see what volume of water is displaced.
Find the circumferrenceThen divide that by the diameterMeasure the shapes' anglesMultiplyThats how you find the liqiud volume of a shape.
length*heigh*width
Solids have definite shapes and definite volume.
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 can't. Volume is only for 3 dimensional shapes. You won't find a way of using volume in any kind of 2 dimensional stuff.
Yes many different shapes can have the same volume
Well in general, you can find volume if you have the relevant dimensions. It's much easier for simple shapes. For complicated shapes, it's easier to use other methods. Immersing an irregularly shaped object in a graduated cylinder is a very useful method of finding volume.
You get the Volume by using formulas. There is usually a specific formula to find the volume of each shape. Some irregular shapes may not have a formula.
You divide the mass by density
Try to break it down to regular shapes/objects.
There are many ways to find the volume of irregular shapes, but the most commonly used method is Water Displacement.
A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
