How would you estimate the volume of a human body in cm cubed?

Question

we have to use like scaling and stuff...i don't know it's a physics problem...i think they want us to use something with order-of-magnitude..i'm completely and totally lost and don't know where to start.

Answer 1

Have a big drom of water, let the persom enter it and submerge full.Measure the volume of water displaced and calculate.

Answer 2

You could pretend that the body was a cylinder. You know the height - about 180 centimetres. How wide would you think the cylinder would be? What size trousers do you wear? Mine have a 34 inch waist, which if it was a circle would give a radius of 34 divided by Pi. Convert this to centimetres, then calculate the volume.

You will be nowhere near the correct answer, but you will be less than 10 times the right answer, so that's known as "within an order of magnitude".
