The rock had a mass of 500g and a density of 10 g/cm3. what is the volume of the rock

lets work back. The formula to find density is d= m/v. fill in the values you know.

10 = 500/v

well, we don't need to use a calculator. dividing by ten is going to the left once, and removing one value of ten.

this means you have a volume of 50. 

Hope this helps! :D

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
