Volume of body

[scidude]

How do you find the volume of a human body in a simple, original and accurate way?

...please give me another way other than the "bath". Although there is nothing wrong with that way, my teacher wants us to find another way to find our body volume.

Do you have any suggestions yourself? What have you come up with so far?

To generate a "simple, original and accurate" result, you could start by interpreting "volume" to refer to sound.

[Boerseun]

You can measure your density against that of water. And then weigh yourself. Pure water weighs in at 1gm for every cubic centimeter. So, if you have your weight, you'll have your volume.

[Qfwfq]

And how do you measure the density? By weighing yourself and measuring volume?

[Shekhar]

If you know the density then just divide your wieght by "g" (acc. due to gravity) to have you mass

Is their supposed to be a technical maths formula which can find out your body volume?

Noo... because there are no measurable dimensions of the body.

Just do as Boerseun said. That should work.

First, measure the surface area of your skin. You might do this by cutting out a 1"x1" square of fabric & holding it on your skin to mark out a numbered grid, then simply the count of squares is your surface area in square inches. Now break your body parts into idealized geometric forms, such as cylinders for fingers & neck, cones for the limbs, and an oblate spheroid for the head. Now apply your measurements of surface area to each idealized region & do the math to calculate the volumes. Sum these, & you have the approximate volume of your body.:)

Make a plaster mold of yourself. After drying, the mold should be split into two pieces, cut very carefully by a trained professional with a very sharp knife or a normal guy with a blunt one.

 

The two pieces should then be reassembled (after you got out, obviously), and the seam sealed with silicon or some other waterproof sealant. A hole should be drilled in the top of the mold's head.

 

Take a measuring jug and fill the mold with water through said hole, measuring litre for litre as you pour the water in. Remember not to lose count, it will waste a lot of time draining the mold without a second air hole. When the water starts spilling out the hole on top of the head, you're done. The amount of litre jugs you've used up to this point will tell you to the litre what your body's volume is - plus the amount of the last jug you've chucked in, to the milliliter. Voila!

 

Note: When making the mold, nudity is optional, but will definitely give a more accurate result.

 

Note 2: Nowhere here have you got into a tub of water, have you?:)

Oh man Boerseun.

Is there no end to your creative humor?:)

As Boerseun suggests, a very easy way to measure of the volume of a human body it to weigh it, convert weight to mass (most scales do this automatically, by having a “kg” scale or setting, and divide by the density of water (1000 kg/m^3). Most human beings have an average density about equal to water – if you’re capable of either floating or sinking in a fresh water swimming pool by filling or emptying you lungs of air, your volume is sufficiently variable that your average density varies from less than to greater than that of water.

 

If this isn’t original enough, think of something wild. For example:

1. Find or build a corrugated cardboard box able to fully enclose your body
   
2. Lay it long-ways on the floor
   
3. Lie in it
   
4. Have someone fill it level to the top with foam packing “peanuts” (you can get large volumes of these for cheap)
   
5. Get out of the box
   
6. Cover the top with clear packing tape
   
7. Upend it
   
8. Measure the height of the peanuts
   
9. Measure the total length, width and depth of the box
   
10. Calculate the volume of the box, minus the volume of the peanuts. This is the volume of your body.
    

Be original! Can you think of a way to use inflated trash bags?
