We can calculate density using the formula. Density also has a general meaning of how much per single unit. So the ground is dense with weeds means there are a lot of weeds per square meter or other unit measure.
Multiply this number by the number of pounds to get the weight in grams.
The equation for this relationship is. P is the population number. Bayes formula particularised for a Machine Learning model and its relevant data. For example the density of water is 1 gram per cubic centimetre and Earths density is 551 grams per cubic centimetre.
