Before you use the answer
Keep a measurement sheet separate from the purchasing allowance. Record which dimensions are internal, which openings were subtracted and which items must be bought as full packs. These are material and schedule estimates; they do not establish structural adequacy or building-code compliance.
An area-only estimate does not solve joint layout, orientation or reusable offcuts.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
