What is an irregular three dimensional shape?
* * * * *
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.

How do you do volume of a irregular shape that is two dimensional?
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.
