Answer:
[tex]\boxed {\boxed {\sf 10 \ g/cm^3}}[/tex]
Explanation:
We are asked to find the density of a cube. The density of a substance is its mass per unit volume. The formula for calculating density is:
[tex]\rho= \frac{m}{v}[/tex]
We know the mass of the cube is 80 grams. We don't know the volume of the cube, but we can calculate it using the following formula.
The side length (s) of the cube is 2 centimeters. Substitute this value into the formula.
- [tex]v= (2 \ cm)* (2 \ cm)* ( 2 \ cm)[/tex]
Now we know the mass and volume of the cube. We can substitute the values into the density formula.
[tex]\rho= \frac{80 \ g }{8 \ cm^3}[/tex]
Divide.
[tex]\rho= 10 \ g/cm^3[/tex]
The density of the cube is 10 grams per cubic centimeter.
