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.

Use the manufacturer's coverage for the actual surface. Porosity and application method affect consumption.

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.
