# You need a cube of aluminum with a mass of 7.6 g. What must be the length of the cube's edge (in cm)? (The density of aluminum is 2.698 g/cm3.)

Interpretation Introduction

Interpretation: The length of aluminum metal to be identified.

Concept Introduction:

Density: Is a characteristic property of a substance.  The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).

Density = MassVolume

Explanation

The length of aluminum metal is calculated as,

Calculate the length of aluminum metal:
