Find the mass using a scale. Find the volume by the water displacement method. Divide mass by volume and that equals density.
You probaly read what i wrote earlier gregorS, if not, type in "how to find the density of a large rock" heheheheheheheh HAHAHAHAHAH MWOHAHAHAHAHAH!
You can find a rock's density in many different ways. That object has a high density and will not float on water.
it's impossible
South Africa has a quite a lot of rock art. The Drakensberg mountains have the highest density of rock art.
The density of an object is constant, therefore, no rock can have less density in water.
The simplest way is to use the formula: P = m / V Density = mass / volume So to calculate the denisty of the rock you will have to find out how much it weighs and how much volume it occupies. You can measure the weight by placing the rock on a weighing scale, this will give the weight in grams. You can determine the volume by submerging the rock in a measuring cup partially filled with water and measuring how much the volume increases. This will give the volume in cm3 Now use the formula to calculate its density in g/cm3.
density is mass per volume. First weigh (mass) the key, then to find it's volume, place it into a container with liquid and measure how much volume is displaced.
There are a number of tools that are needed to find the density of a rock. You will mainly need a scale to measure the weight and the volume of the rock. Divide the mass of the rock by the volume to find the density.
A rock
Rock density has no direct affect on war.
The rock's density is 3 g/cm3
Determine its volume by how much water it displaces, then divide mass by volume
