well one of the formulae is:
Density = 3g/4G*(py)*r
where
g = gravitational acceleration
G = universal gravitational constant
py = 22/7 or 3.14
r = radius of the planet (half the diameter)

Plant density can be calculated by dividing the total number of plants in an area by the total area size. The formula is: Plant density = Number of plants / Area size. The unit of measurement for plant density is typically plants per square meter or square foot.
The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
You can determine the density of a liquid by measuring its mass and volume, then calculating the density using the formula density = mass/volume. The liquid with the highest density will sink to the bottom when layered with other liquids of different densities in a container.
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
density=mass/volume d=m/v
