Simple math.
Visible assumptions.
(Length × width × count − openings) × thickness
Measure length and width in feet, and thickness in inches. For different-sized surfaces or thicknesses, calculate each group separately and add the raw board feet.
This calculation does not establish required R-value, account for framing thermal bridges, or set a product’s lift limit. Confirm the assembly and installation requirements before turning volume into a purchase.
