Hopefully there's a scientist here or someone else who can answer this.
Lets say a person with active and tranmissible COVID was to breath into a clean plastic cube for a couple minutes, then seal it up. Do scientists have some sort of method of measuring the amount of virus that was left in the box?

If you'd like to find out how airborne viruses are measured, I recommend doing a search in the
PubMed database
and reading primary journal articles' Materials and Methods sections. Start with metadata review articles (ones that review many previously published papers). Clicking to open any of them will show you lots more to read - enjoy the rabbit-hole.

Summary: To better understand the underlying mechanisms of aerovirology, accurate sampling of airborne viruses is fundamental. The sampling instruments commonly used in aerobiology have also been used to recover viruses suspended in the air. We reviewed over 100 papers to evaluate the methods currently used for viral aerosol sampling. Differentiating infections caused by direct contact from those caused by airborne dissemination can be a very demanding task given the wide variety of sources of viral aerosols. While epidemiological data can help to determine the source of the contamination, direct data obtained from air samples can provide very useful information for risk assessment purposes. Many types of samplers have been used over the years, including liquid impingers, solid impactors, filters, electrostatic precipitators, and many others. The efficiencies of these samplers depend on a variety of environmental and methodological factors that can affect the integrity of the virus structure. The aerodynamic size distribution of the aerosol also has a direct effect on sampler efficiency. Viral aerosols can be studied under controlled laboratory conditions, using biological or nonbiological tracers and surrogate viruses, which are also discussed in this review. Lastly, general recommendations are made regarding future studies on the sampling of airborne viruses.
