A soil sample was taken using a cylindrical core. The soil and core weighed 230 g. The mass of the core sampler is 78 g, has a height of 5 cm, and a diameter of 5 cm. After oven-drying at 105 Celsius, the soil and the cylindrical core weighed 204 g. What will be the volume of water in a 2-hectare field in m³? Assume 1g/cm³ for the density of water, 2.65g/cm³ for particle density, and 65 cm for the depth of soil.
