To measure volume of large irregular shaped objects you need a displacement can
For instance, you might divide the polygons into triangles, calculate the area of each triangle, and then add everything up.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
The eureka beaker is a beaker to find out the density of irregular shaped objects. Archimedes invented it when he stepped into his bath and saw that the water level rose. He shouted "Eureka!" which means "i have found it!".
For any irregular shape, you must divide it into shapes that are regular and find the area of those then add up all of the parts to find the area of the whole.
To find the area of any parallelogram, whether it be irregular or not, just multiply the base by the height. * Ap = bh

There are basically two techniques for finding the area of a shape with uneven or irregularly shaped sides. If the sides can be described by algebraic equations, then integral calculus can be used to find the area. Failing that, you can approximate the irregular shape by fitting in a number of smaller, regularly shaped polygons such as squares and triangles, whose area can be calculated by simple geometric techniques.
To find the area of irregular shapes, first, we need to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth. Then, find the area of these individual shapes and add them to get an area of irregular shap
