How much oxygen is there in a 1meter cube of air?
As the density of Oxygen at 0º C is 1.429 kg/m³ i.e. cubic meters * density = kilograms so, 1 cubic meter of oxygen would weigh 1.429 kilograms.
What is the Working principle of dissolved oxygen meter?
Dissolved Oxygen (DO) is really a physical distribution of oxygen molecules in water. There are two main sources of DO in water: atmosphere and photosynthesis. Waves and tumbling water mix air into water where oxygen readily dissolves until saturation occurs. Oxygen is also produced by aquatic plants and algae as a by-product of photosynthesis. The electrochemical method of measuring DO requires a cathode, anode, electrolyte solution and a gas permeable membrane. The material of the membrane is specially selected to permit oxygen to pass through. Oxygen is consumed by the cathode which will create a partial pressure across the membrane. Oxygen will then diffuses into the electrolyte solution. Thus, a DO meter actually measures the pressure of oxygen in water. It can be used to measure DO in any medium.

Why couldn't a meter stick be used to measure expansion of the rod?
Probably because the meter stick is not accurate enough to measure the small amount of expansion of the rod. You need something smaller and more accurate.
