Example 1. A cylindrical glass column with a capacity of \( 600 . \mathrm{cm}^{3} \) is fully packed with 815 grams of quartz sands. Water is pumped into the sand column at the constant flow rate of exactly \( 13 \mathrm{~mL} / \mathrm{min} \), and it takes \( 15.0 \) minutes to saturate the sand column. Based on the above information, calculated the density of quartz sand.
