Question

The properties of a cube are listed below:

Answer 1

Answer:

10 g/cm3

Explanation:

The density is equal to mass/volume

so Mass is 80g

and volume is 2*3=8

so density=80/8=10g/cm3

Answer 2

Answer:

$\boxed {\boxed {\sf 10 \ g/cm^3}}$

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:

$\rho= \frac{m}{v}$

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.

• $v= s^3$

The side length (s) of the cube is 2 centimeters. Substitute this value into the formula.

• $v= (2 \ cm)^3$

• $v= (2 \ cm)* (2 \ cm)* ( 2 \ cm)$

• $v= 8 \ cm^3$

Now we know the mass and volume of the cube. We can substitute the values into the density formula.

• m= 80 g
• v= 8 cm³

$\rho= \frac{80 \ g }{8 \ cm^3}$

Divide.

$\rho= 10 \ g/cm^3$

The density of the cube is 10 grams per cubic centimeter.
