Question

You have a rock with a volume of 15cm3 and a mass of 45 g. What is its density?

Answer 1

Answer:

density is mass divided by volume, so that the density is 45g divided by 15cm 3 cube, which is 3.0 g/cm 3

Answer 2

The density of the rock is 3 g/cm³

Given : The volume of the rock is 15cm³ and mass is 45g.

To find : The density of the rock.

Solution :

We can simply solve this numerical problem by using the following process. (our goal is to calculate the density of the rock)

Here, we will be using the mathematical formula for calculating the density. Which is :

Density = Mass/Volume

By, putting the given values in the above mentioned formula, we get :

Density of the rock = (45/15) g/cm³

Or,

Density of the rock = 3 g/cm³

(This will be considered as the final result.)

Hence, density of the rock is 3 g/cm³
