3. A sandstone core composed of quartz and feldspar grains with calcite cement is 75 mm in diameter and 160 mm long. On saturation in water, its wet weight is 1900 gr, and after oven drying its weight is 1862 gr. If the specific gravity (G) is equal to 2.7 for this sandstone, calculate the saturated unit weight, the dry unit weight, and the porosity of this core.
