If a shape is two dimensional it has NO volume - volume is an attribute of THREE dimensional shapes.
If you meant the AREA of an irregular two dimensional shape, then divided it up into areas which are not irregular and so you can calculates them, and sum the areas of these non-irregular shapes.
If you meant the volume of an irregular THREE dimensional shape, then a similar process can be followed by dividing it up into three dimensional shapes you can can calculate the volume of and summing them, though if it is an irregular object that you are physically holding, then you can find its volume by finding the increase in volume of a liquid (In a regular container) when the object is submerged into that liquid.

How is the volume of a rectangle measured?
Simple. The volume of a rectangle is 0. A rectangle is a two dimensional shape and therefore cannot have a volume.
What is the definition of an irregular volume?
An irregular volume is one that has no simple equation to describe it's shape. An example would be a cylinder with a cone on it's end. The shape can often be divided into two or more regular shapes which have known equations that describe them. In this case, a cylinder and a cone. To then find the total volume of the irregular shape, you sum the volumes of the individual regular shape volumes.
What is the formula to get the volume of a triangle?
There is none because a triangle is a 2D shape and volume measures 3D shapes ----------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
What is an irregular three dimensional shape?
a triangle * * * * * Wrong on at least two counts: A triangle need not be irregular and a triangle is not a three dimensional shape. Any pyramid other than a regular triangular pyramid (tetrahedron), any prism other than a cube are some examples.
What is the formula for finding the volume of a rectangle?
Rectangles, being two-dimensional objects, do not have volume. Rectangular prisms, on the other hand, do. The equation for their volume is length*width*height, or lwh.
