I need a help with modulus of elasticity and down.

Extracted text: During a site investigation, a boring was advanced to a depth of 10 m at which rock was encountered. The water table was never encountered during the investigation. The engineering geologist cored 5 m into the rock. The amount of recovered rock was 3.0 m in pieces of 10 cm or longer in length. An unconfined compression test was conducted on a specimen (area 50.3 cm) of the rock core. The ultimate compressive breaking load was 50,505 kg. The strain at 50% of the unconfined oompressive strength was equal to 0.0030 mm/mm. Using an RQD value of 65% and unconfined compressive strength of 105 MPa determine the Rock Mass Rating for the site where a slope is being evaluated using the following infomation. The spacing of the discontinulties were found to be 210 mm apart and consisted of slightly weathered, slightly rough surfaces separated by less 1mm. The rock mass is damp. The strike and dip orientations of discontinuities are considered favorable for a slope. Based on the information given, provide the following quantities or descriptions. Round your calculations to the nearest whole number. Rock Quality Designation: 60 Description of rock quality: fair Unconfined compressive strength: 1004 Modulus of elasticity: Modulus ratio: Strength classification of the intact rock: Modulus of elasticity classification of the intact rock Rock Mass Rating Class Number (report as an integer, e.g. 1, 2, 3, 4, 5) Description
