Questions about flooring calculator

Why does the number of packs round up?

Materials are purchased in whole packs. A 20 m² floor with 10% waste needs 22 m²; at 2 m² per pack that is 11 packs. Choose a supported area shape or enter a measured area for a more complex room, and check your layout before ordering.

What assumptions should I check?

One rectangular area. Allow for layout, cuts, batch matching, and installation costs separately.
