The correct answer is: 5 kg/m3
To find the density of a cube, you need to divide the mass by the volume. The volume of a cube is given by the formula V = s^3, where s is the length of a side.
Given that the side length of the cube is 2 meters, the volume can be calculated as follows:
V = 2^3 = 8 m^3
Now, divide the mass of the cube (40 kg) by the volume (8 m^3):
Density = mass/volume = 40 kg / 8 m^3 = 5 kg/m^3
Therefore, the density of the cube is 5 kg/m^3.
