Problem 4P

(I) State your mass and then estimate your volume. [Hint Because you can swim on or just under the surface of the water in a swimming pool, you have a pretty good idea of your density.)

Solution 4P:

We have find the volume of the person (yourself) using laws of flotation, if it just swim on or under water.

Step 1 of 3

Concept:

If an object floats just under the surface of the water, then the density of the object must equal to the density of the water.

The ratio of the mass of an object to its volume is always constant, and it is known as the density of that object. Mathematically,
