Answer:

The piece of metal found by the student is not aluminium.

Step-by-step explanation:

First we calculate the density using the following formula:

density = mass (g) / volume (cm³)

Now the density of the metal piece:

density = 612 g / 245 cm³ = 2.49
(g)/(cm^(3))

The density of aluminium is 2.7
(g)/(cm^(3)) so we may conclude that the particular piece of metal found by the student is not aluminium.
