Given:
volume of the rock is

The mass of the rock is

Required: Density of the rock is to be calculated
Step-by-step explanation:
To calculate the density of the rock we will use the formula that is given as

first, change the respective quantities in SI form
then volume of the rock is

Similarly for mass of the rock
then

plugging all the values in the above relation, we get

Thus, the density of the rock is
