To find the dry unit weight of the soil, we can use the formula:Dry unit weight = (Total unit weight) / (1 + (Specific gravity) * (Water content))Given:Total unit weight = 22 kN/m^3Specific gravity = 2.67Water content = 10% = 0.1Substituting the values into the formula:Dry unit weight = 22 / (1 + 2.67 * 0.1)Dry unit weight = 22 / (1 + 0.267)Dry unit weight = 22 / 1.267Dry unit weight ≈ 17.41 kN/m^3Therefore, the dry unit weight of the soil is approximately 17.41 kN/m^3.
