An air conditioning system can circulate 530 cubic feet of air per minute. How many cubic yards of air can it circulate per minute?

To convert cubic feet to cubic yards, divide the volume in cubic feet by 27, since there are 27 cubic feet in one cubic yard. Therefore, if the air conditioning system circulates 530 cubic feet of air per minute, it can circulate approximately 19.63 cubic yards of air per minute (530 ÷ 27 ≈ 19.63).
