## Debris in the Ocean

One of the problems with debris in the ocean is that it is often difficult to see, because much of the object is under the surface of the water. An object with a density of 911 kg/m3 and a mass of 2227 kg is thrown into the ocean.

Find the volume of the object sticking out of the water (use ρsea water = 1024 kg/m3)

Find the volume of the object sticking out of the water (use ρsea water = 1024 kg/m3)

**help**

could some one help me I thought I was doing this problem

correct but apparently I'm not

I did

density of object/density of salt water = fraction of

volume underwater

therefore, fraction above water is 1-fraction of vol.

underwater.

yeah i was trying to follow example 10.7 in the book on page

326 but I am still confused on how to solve this problem

*Anonymous 3*

(density of the object/density of the water)*vol. of the object

this will give you the vol. under water.

to find the vol. above water take the the total vol. of the object and subtract the

vol. under water.

to find vol. of the object take the mass and divide it by the density.

can someone please explain it more clearly... there is not volume given in the

problem so im not sure where you are getting the values.. thanks

**Re:**

How did you find the volume of the object?

*Anonymous 6*

what are the units?

**NEW**

**easy way...**

*Anonymous 7*

v=(mass*g)/(1024*g)

x=mass/density of object

x-v=final answer
