A flooring company compares ceramic tiles with polymer tiles used to cover the same area of floor. The company claims that the polymer flooring has a lower environmental impact.
The company uses the data in the table.
| Flooring | Mass per m² in kg | Energy used in manufacture in MJ/kg | Mass sent to landfill per m² in kg |
|---|---|---|---|
| Ceramic | 18.0 | 6.0 | 15.0 |
| Polymer | 7.0 | 14.0 | 1.4 |
Calculate the energy used to manufacture 1 m² of each flooring.
