To determine what metal the sample might be, we need to calculate its density. Density is mass divided by volume.

Step 1: Identify the mass and volume. From the question, we know that the mass (m) is 13.5 grams and the volume (V) is 5 cm³.

Step 2: Use the formula for density (D), which is D = m/V.

Step 3: Substitute the given values into the formula. D = 13.5 g / 5 cm³ = 2.7 g/cm³.

Step 4: Compare this density with the densities of known metals.

Aluminium has a density of 2.7 g/cm³, so the unknown substance could be aluminium.
