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)
2.70×10-1 m^3

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

(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

How did you find the volume of the object?

what are the units?

easy way... Anonymous 7
v=(mass*g)/(1024*g)
x=mass/density of object
x-v=final answer
