Assuming it is a round marble (spherical actually) one first has to weigh it. Next one has to measure its diameter using a micrometer or a vernier scale. Halve the diameter to obtain the radius R. The volume can then be calculated by using the equation 4/3 x pi x R x R x R. Pi can be taken as being 22/7 or 3.142
Density is mass divided by volume and on the surface of the earth, mass and weight are usually regarded as being the same (not strictly true but near enough)

Water has the density of around 1000 kilograms per cubic meter or 1.000 g/mL.
The density of marble can be between 2.4 and 2.7 grams per cubic centimeters. Marble is a metamorphic rock that is composed of calcite. Marble develops from limestone.
.5 gm/cm cubed
Which is not possible ... it's half of water's density.
2.563 kg per millimetre cube

234kg
The density of the marble is about 4.94 g/cm3
density=mass/volume
We know the size (volume) of the planet AND its mass. Density is mass divided by volume.
When pressure increases the volume of the material decreases. Density=mass/volume When volume decreases density increases.(Mass constant)
density is the constant found by dividing the mass (in grams) by the volume in centimeters cubed (sometimes milliliters). other units are possible but are not common in science classes. every substance has a set density, that never changes. the more you have in mass, the same higher proportion of volume comes with it. the density of pure water is 1.000 gram per cm3 the density of copper is 8.960 grams per cm3
The density of the marble is about 4.94 g/cm3
What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?

Since density is mass per unit volume, the density is the same.
Mass is a meause of density times volume. Therefor, mass= density x volume, and density = mass/volume. You divide 243 into 994. The answer to your question is approximately 4.13 grams per cubic cm.
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
You are supposed to divide the mass by the volume.
Density = Mass/Volume = 3.050/[4/3*pi*r3] = 2.91 grams/cm3
The density of the marble would be determined by dividing the marble's mass (12.5 g) by its volume (5ml), which would give you 2.5g/ml.
divide the mass over the volume and the answer is 2.3 D=M over V D=23 over 10=2.3.
Denisty = mass/volume. 13/5 and then convert your units as need be.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
