How much concrete 1m2?

To determine how much concrete is needed for 1 square meter (m²) of surface, you also need to specify the thickness of the concrete layer. For example, if you want a thickness of 10 centimeters (0.1 meters), you would calculate the volume as 1 m² x 0.1 m = 0.1 cubic meters. Therefore, for a 10 cm thick layer, you would need 0.1 cubic meters of concrete for 1 m².
