how do i find the volume of an irregular?

Question

i am doing a math project, and for the volume do i just find out the sides its 1 inch thick (the wood/shape).

Answer 1

the easiest way to find the volume of an irregular object is to fill a measureable volume of water and then submerge the object and look at the amount of water that was displaced by doing so.

Answer 2

You will have to divide the irregular shape into a series of triangles or other figures, if possible, and then make all necessary measurements to compute all areas and comput their sum. Then volume = total area *1 in^3.
