Cubic feet convert to square feet only when thickness or depth is known. Formula: ft² = ft³ ÷ thickness (ft). Example: 1 ft³ spread 1 inch thick covers 12 ft²; 2 ft³ at 2 inches covers 12 ft².
Enter volume in cubic feet (ft3):
If the thickness (height) is measured in inches (in)
Enter thickness (height) in inches (in):
The area in square feet is:
0.00ft2
If the thickness (height) is measured in feet (ft)
Enter thickness (height) in feet (ft):
The area in square feet is:
0.00ft2
How to convert from cubic feet (ft3) to square feet (ft2)?
If the thickness (height) is measured in feet (ft):
To convert cubic feet (ft^3) to square feet (ft^2), cubic feet must be divided by the thickness in feet (ft).
ft2 = ft3 / ft
If the thickness (height) is measured in inches (in):
To convert cubic feet to square feet, cubic feet must be divided by the thickness in inches and multiplied by 12
ft2 = (ft3 /in)*12
