The density of the aluminum is 3 g/cm³
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance.
[tex]Density = \frac{Mass }{Volume }[/tex]
To obtain the density of the aluminum, we'll begin by calculating the volume of the aluminum. This can be obtained as follow:
From the question given above, each side of the aluminum cube measures 3 cm. Thus,
Length (L) = 3 cm
Width (W) = 3 cm
Height (H) = 3 cm
Volume = Length × Width × Height
Volume = 3 × 3 × 3
Volume = 27 cm³
Therefore, the volume of the aluminum is 27 cm³
Finally, we shall determine the density of the aluminum. This can be obtained as follow:
Mass = 81 g
Volume = 27 cm³
Density =?
[tex]Density = \frac{Mass }{Volume }\\\\Density = \frac{81}{27}[/tex]
Density = 3 g/cm³
Therefore, the density of the aluminum is 3 g/cm³
