The formula to calculate the Rock Density (RD) is:
\[
RD = \frac{RM}{RV}
\]
Where:
\( RD \) is the Rock Density (lbs/ft³)
\( RM \) is the rock mass (lbs)
\( RV \) is the rock volume (ft³)
Definition
Rock Density (RD): The density of the rock, measured in pounds per cubic foot (lbs/ft³).
Rock Mass (RM): The mass of the rock, measured in pounds (lbs).
Rock Volume (RV): The volume of the rock, measured in cubic feet (ft³).
Significance: Calculating the rock density is important in geology and construction. It helps in understanding the properties of the rock, such as its strength and stability, which are crucial for various applications.
Example
Let's say the rock mass (RM) is 150 lbs and the rock volume (RV) is 3 ft³. Using the formula:
