The correct density of the cube is 5 kg/m^3.
To calculate the density of an object, you divide its mass by its volume. The formula for density is:
Density = Mass / Volume
In this case, the mass of the cube is given as 40 kg, and the cube has a side length of 2 meters.
To find the volume of the cube, you need to calculate the volume of a cube using the formula:
Volume = Side Length^3
Plugging in the values, we have:
Volume = 2^3
Volume = 8 cubic meters
Now, we can calculate the density by dividing the mass by the volume:
Density = 40 kg / 8 cubic meters
Density = 5 kg/m3
Therefore, the density of the cube with a side length of 2 meters and a mass of 40 kg is 5 kg/m3.
