A rock core has been collected for a site investigation project. The whole length of the core comprises pieces/sections that have lengths and conditions given in Table \( 1 \mathrm{~A} \). Table 1A: Drill core section lengths and conditions a) Calculate the RQD for the drill core given above. (4 marks) Note: \( R Q D=\frac{\sum \text { length of core pices }>10 \mathrm{~cm} \text { length }}{\text { total length of core run }} \times 100(\%) \)
