A triaxial test on a sandstone sample is conducted at a confining pressure of 10 MPa. The elastic axial and volumetric strains at axial stress of 50 MPa are recorded to be 4.2×10-3 and 2.0×10-3 respectively. The modulus of elasticity, in GPa, and Poisson's ratio of the sample, respectively are closest to
