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
