in a uniform solid it would be the natural center of gravity.
in a non solid or composite structure it may not lay within the boundary of said shape

If you were to throw it up in the air and watch the axe(s) that it rotates about you would have the answer...
Obviously that is impractical.
If it were magnetic you could float it on a piece of Styrofoam in the bathtub and pull it around with a magnet, getting it to circle,
that would give you a rough idea in one plane. Then rotate the object 90 Deg in any axis and repeat to get a rough idea in another plane.
Someone watching either the tossed object or the floated object with a camera, would greatly assist.
However if the object is your car or a cement truck things are a little more tricky. There you can approximate by weighing each axle separatly, then measuring their positions. That gets one plane. the other is much harder, You could get a fairly good idea by putting both driver side wheels on a scale getting a number, then jacking the pass side up by say 1 foot and re-weighing the drivers side.
This could be impractical if you are trying to determine the center of gravity of say a submarine, or and asteroid.
Then you need to know more about the object Spacial density, and shape and use some good old calculus.

It depends on the object and the mass distribution. There is no 'usual' place for it. It might not even be on the object.

within the object

use cortetian graph

x= ( sum of m*x)/sum of m

same for y

if two items together

look at momentum section in your textbook\

otherwise there is an integral equation
