To find the density of the rock sample, you can use the formula:

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

Given:

• Mass = 360 grams
• Volume = 120 cubic centimeters

Substituting the values into the formula:

$\text{Density} = \frac{360 \text{ grams}}{120 \text{ cubic centimeters}} = 3 \text{ grams per cubic centimeter}$

Thus, the density of the rock sample is $3$ grams per cubic centimeter.

Would you like any further details or explanations? Here are some related questions you might find interesting:

1. How would the density change if the mass or volume were different?
2. What are some common densities of various materials for comparison?
3. How does temperature affect the density of a substance?
4. What is the significance of density in identifying materials?
5. Can density be used to determine the composition of a rock sample?

Tip: When measuring density, ensure that the mass and volume are in compatible units to get accurate results.
