How to Calculate the Density of Aluminum?

What is the density for aluminum in g/cm3?

A small cube of aluminum measures 15.6 mm on a side and weighs 10.25 g.

Calculation of Aluminum Density

To calculate the density of aluminum, we need to determine the volume of the cube and divide the mass by that volume.

Density is defined as the mass per unit volume of a substance. In this case, the small cube of aluminum has dimensions of 15.6 mm on each side and a weight of 10.25 g. The density of aluminum is approximately 3.35 g/cm³.

The volume of a cube can be calculated using the formula: Volume = side^3.

Given that the side length of the cube is 15.6 mm, which can be converted to centimeters by dividing by 10: Side length = 15.6 mm / 10 = 1.56 cm.

Plugging the side length value into the volume formula, we get: Volume = (1.56 cm)^3 = 3.06 cm³.

Next, we divide the mass of the cube by its volume to obtain the density: Density = mass / volume = 10.25 g / 3.06 cm³ ≈ 3.35 g/cm³.

Therefore, the density of aluminum is approximately 3.35 g/cm³.
