How to convert from cubic feet (ft3) to square meters (m2)?
The volume in cubic feet (ft3) should be divided by the thickness in feet and divide by 10.76. The result is an area in square meters (m2).
1 ft = 0.3048 m ⇒ 1 m = 1/0.3048 ft
m2 = (ft3 / ft) / (1/0.3048*1/0.3048) = (ft3 / ft) / 10.76391
m2 ≈ (ft3 / ft) / 10.76
Area square meters = ( Volume cubic feet / Thickness feet) / 10.76
