Question 174229: When a chunk of metal is dropped into a container of water, the water level rises 1.8cm. The container is shaped like a prism, with a base that measures 3cm on each side. What is the density of the metal if its mass is 45 grams? The answer is in grams/cm to the third.

density equals mass divided by volume
:
D=m/V
:
The volume of the displaced fluid is the same as the volume of the object, so can figure the volume of the object.
:
we are given the mass at 45 grams
:
the volume would be the same as the displaced water which is
:
Volume of metal and displacement: 3%283%29%281.8%29=16.2%28cm%29%5E3
:
so D=45%2F16.2=2.78%28g%2Fcm%5E3%29
