First answer is correct. second good advice (however you would be better using a measuring flask and check before and after you enter the rock.)
Can't do calculations? Use a calculator.
Remember the formula!

Nice job, Chrissy !!
BTW, to get a volume of an irregularly shaped object (like a rock), fill a bucket right to the brim with water and then put the object in the bucket and measure the volume of the overflow. Archimedes thought of this one day getting into the bathtub.
Ain't science great?

It's really a Physics subject. As the Gallon is a unit of volume (but, an unusual one for rocks), then...500lbs/1.35lbs/gallon = 370.4 gallons. Yet another perfectly correct answer gets a 'thumbs down'...Anyone like to explain Why ???

Density = Mass/Volume
And there's nothing wrong with your spelling....

density=mass/volume
so.. 454g/100cm3= 4.54g/cm3
