Well, we have no idea how big you are :smile: but perhaps you could imagine trying to squeeze a full-size replica of yourself into as short as possible a length of round pipe. So for ease of transport, you could remove both arms and lay them along your legs. Perhaps remove both feet and pack them around your neck. How long and how round would you estimate the final cylindrical package to be?

Now determine the volume of that cylinder, in cm^3.

For greater accuracy, maybe you could separately estimate the dimensions of your leg as a cylinder, your arm, and your torso, then use arithmetic to get your final answer, allowing a bit more for your head.
 
I have a very simple method that will give a good first approximation but this is a homework problem and you have not shown any effort yet.
 
For quite a rough estimate, you can approximate your body as a bag of water and use the proportion, for water, 1kg →1 L.

CAF123, the general rule on this forum is to insist that an OP show SOME attempt to solve a problem themselves before we chime in. We are not here to spoon-feed people answers, as that doesn't help them learn how to think.

I am well aware of the forum rules, I just thought that since a method approximating the body as a volume of cylinder was introduced, I would give another way. On reflection, maybe yes, I should have waited - all I can do is apologise.
