To calculate the density, you can use the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
First, determine the volume of the cube. The volume \(V\) of a cube with side length \(s\) is given by:
\[ V = s^3 \]
For a cube with a side length of 2 meters:
\[ V = 2^3 = 8 , \text{m}^3 \]
Now, plug the mass (40 kg) and the volume (8 m³) into the density formula:
\[ \text{Density} = \frac{40 , \text{kg}}{8 , \text{m}^3} = 5 , \text{kg/m}^3 \]
So, the density of the cube is 5 kg/m³.

The volume \(V\) of a cube can be calculated using the formula:
\[ V = s^3 \]
where \(s\) is the side length of the cube.
For a cube with a side length of 3 centimeters:
\[ V = 3^3 = 27 , \text{cubic centimeters} \]
Thus, the volume of the cube is 27 cubic centimeters.
