To answer this you need to know the density of Olive oil and the density of the plastic.
Olive oil has a density of between 0.8 - and 0.92 at standard room temperatures (you can look this up on the web).
Your plastic object has a volume of 4 times 2 times 3 = 24 cubic centimeters and weighs 19.2 grams.
One cubic centimeter of the plastic would therefore weigh 19.2 divided by 24 = 0.8 and this value is also its density (grams per cc).
Thus the answer is that the plastic would float on the dense type of Olive oil but would be neutrally buoyant in the less dense types.
yes, a device known as micrometer is used for this purpose.

There is no "unit of measurement for a plastic block". The SI has units of length, area, volume, mass, tensile strength, etc.; please clarify what aspect of the plastic block you want to measure.
Plastic.. Depends what type, but plastic pipes are made from plastic. :)
no, plastic is made out of oils usually petroleum.

It doesn't matter what material it is.
There's a graduated cylinder to measure liquid volume. It is a clear glass or plastic tube with mL markings on it.

for a low tech method, simply put a plastic container outside whilst it is raining, measure how much rain has fallen once it has stopped.
