b) The grain size analysis is widely used in the classification of soils. The data obtained from the analysis helps design various engineering projects related to soil including earth dams. As a site engineer, you are responsible for investigating the soil grain size distribution aty has performed the sieve analysis method. The weight of the soil sample use is 617 g and the analysis results are as shown in Table 1.
