What would be the best method to measure the total population density of a dense bacterial culture in a petridish and why?

Measuring the biomass or percent cover rather than the number is the most accurate way to determine the total population density of a dense bacterial culture in a petridish. This is due to the fact that counting the population of a thick bacterial culture would either be impossible or take a long time.
