The density of the metal cube is 2.703 g/cm³.
The mass of a metal cube is m =50.3 grams.
The edge length of the metal cube is l = 2.65 cm.
Now, the density (ρ) of a cube can be given as:
ρ = m/(a)³
Where (a)³ is the volume of the cube, m is the mass of the cube, ρ is the density of the cube, and a is the length of one side of the cube.
Since the sides of a cube are equal therefore the value of a is the same for each edge length of the cube.
Now, the density of the metal cube in g/cm³ is:
ρ = m / a³
ρ = m / l³
ρ = 50.3 g / (2.65 cm)³
ρ = 50.3 g / (2.65 cm)(2.65 cm)(2.65 cm)
ρ = 50.3 g / 18.609 cm³
ρ = 2.703 g/cm³

Answer:
To save the unnecessary bills and carbon emissions.
Explanation:
Energy efficiency is important to society in the following ways:
1. It saves the unnecessary bills as buildings who are using energy efficiently have less demands.
2. Saving energy for the future generations as we know low demand would save the sources.
3. Energy efficiency is also important to society in environmental ways at efficient energy means low carbon emissions.
Mr. Roentgen's x-rays allowed scientists to measure the size of the atom. The x-rays were small enough to discern the atomic clouds. This was done by scattering x-rays from atoms and measuring their size just as Rutherford had done earlier by hitting atoms with other nuclei starting with alpha particles.
