| Measured sections | [{"length":5,"width":4}] | |
|---|---|---|
| Room height | 2.5 | m |
Method and assumptions
room_volume_m3 = sum(length_m * width_m) * common_height_m
Floor area is the sum of section areas; volume multiplies that area by the common height. Shared edges are not included in a perimeter estimate.
Wall area sums length × height × count. Measure door and window openings; do not subtract an opening twice.
Example with the selected inputs
- Floor area: 20 m²
- Room volume: 50 m³
Change the inputs to match your own task. Whole packages are rounded up after allowances, so purchase quantity and actual requirement can differ. Apply each allowance once.
