Explanation:
We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.
![\rho= \frac{m}{v}](https://tex.z-dn.net/?f=%5Crho%3D%20%5Cfrac%7Bm%7D%7Bv%7D)
The mass of the brick is 100 grams and the volume is 25 cubic centimeters.
Substitute the values into the formula.
![\rho= \frac{ 100 \ g}{25 \ cm^3}](https://tex.z-dn.net/?f=%5Crho%3D%20%5Cfrac%7B%20100%20%5C%20g%7D%7B25%20%5C%20cm%5E3%7D)
Divide.
![\rho=4 \ g/cm^3](https://tex.z-dn.net/?f=%5Crho%3D4%20%5C%20g%2Fcm%5E3)
The density of the brick is <u>4 grams per cubic centimeter.</u>
