use calculus and integrate or fill it with water and measure.
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.
An equilateral triangle is a regular shape because it has 3 equal sides.
A tetrahedron is not an irregular triangle, it is a three dimensional shape, the simplest form of pyramid, with 4 triangular sides.
The best way to find the volume of an irregular shape is to split it up into shapes that you know, find the volumes of those individual pieces, and then add up all of the volumes of the split pieces to get your total volume of the irregular shape.

To find the density of an irregular shape, you will first need to measure its mass using a scale. Next, you will need to find the volume of the shape, which can be done by water displacement method or by using a formula suitable for the shape. Finally, divide the mass by the volume to calculate the density of the irregular shape.
Asymmetrical. The answer is NOT irregular. An irregular shape, such as an isosceles triangle does have an axis of symmetry.
A scalene triangle is an example of an irregular shape
To calculate the density of an irregular object like a rock, you can measure its mass using a scale and then determine its volume using the water displacement method. Once you have the mass and volume, you can divide the mass by the volume to obtain the density of the rock.
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
You use disfigurasation
To find the volume of an irregular shape object, you can use the water displacement method. Submerge the object in a container of water and measure the increase in water level, which corresponds to the volume of the object. Alternatively, you can break down the object into smaller regular shapes, calculate their volumes, and then sum them up to find the total volume.
We get the idea that an "irregular sphere" is not a sphere. At that point, we knowexactly what it isn't, but not much yet about what it is. So you have to reveal a lotmore about it before anyone can calculate its volume. Like, for example, less infoabout what the object is not like, and more definition of its actual shape.
