Question

The body of the cuttlefish contains a porous bone that has a density of 0.50 g/cm3. The rest of its body has a density of 1.067 g/cm3. What is the percentage of the body volume X occupied by the porous bone that makes the average density of the fish be the same as the density of water 1.0 g/cm3.

5/5

Answer 1

For an object to sink in something, it's

density has to be higher than the object it

is in, so if it sinks in water the number has

be higher than 1

And to float, and objects density has to

be lower than that of the substance it is

put in, so it has to be lower than 1.26
