An attic with an area of 600 square feet with ridge and soffit vents should have a total vent area of _____ square feet?

To determine the appropriate total vent area for an attic with a given square footage, one commonly used guideline is that the total vent area should equate to approximately 1 square foot of vent area for every 150 square feet of attic space. This guideline is designed to ensure adequate airflow, which is crucial for preventing moisture buildup and promoting proper ventilation, thus reducing the risk of mold growth and structural damage.

In this scenario, with an attic area of 600 square feet, the required total vent area can be calculated by dividing the attic space by 150:

600 square feet ÷ 150 square feet per vent = 4 square feet of vent area.

This indicates that an attic of this size actually requires about 4 square feet of vent area to maintain effective ventilation. Therefore, any value that isn't close to this calculated need, such as 2, 6, or 8 square feet, would not meet the adequate ventilation requirements. The correct answer should be aligned with the calculation provided for optimal attic ventilation.
