To find the cube's mass, you can use the formula: Density = Mass/Volume. Rearranging this formula, we can solve for the mass:
Mass = Density * Volume
Given that the density of aluminium is 2.7 g/cm³ and the cube measures 10 cm on each side, we need to calculate the volume first.
The volume of a cube is given by the formula: Volume = Side^3
In this case, the side length is 10 cm, so we substitute it into the formula:
Volume = 10 cm * 10 cm * 10 cm
= 1000 cm³
Now we can calculate the mass using the formula:
Mass = Density * Volume
= 2.7 g/cm³ * 1000 cm³
= 2700 g
Therefore, the mass of the aluminium cube is 2700 grams.
