Depends What measurement you want it in, if u want it in cm2 then multiply 14x24=336cm2 so that's your answer in cm2. your welcome! ^.^
geometric mean of 14 and 24=√(14x24)=√336=4√21
it's 14x24, which is 336 square feet
For a 2.5-ton AC unit, a typical return air vent size would be around 20x20 inches or 14x24 inches, depending on the specific airflow requirements and duct design of the system. It's important to calculate the total airflow needs, which is generally around 400 CFM (cubic feet per minute) per ton, to ensure adequate ventilation. Consulting with an HVAC professional can help determine the exact size needed for optimal performance.
Well, honey, 14 times 24 is 336. But if you're asking about square feet, that's a whole different ball game. You see, square feet is a unit of area, not just a simple multiplication problem. So, to find the area in square feet, you need the dimensions in feet.
