Calculation Results
Density Formula: ρ = m/V
Volume Formula: V = a³ (for cube with side length a)
Calculation: 1.000 kg ÷ 0.000000 m³ = 0.00 kg/m³
Density Analysis
Example: Concrete Cube
Problem Setup
Object: Concrete cube with side length 10 cm
Mass: 2.4 kg
Find: Density of the concrete
Solution Steps
1. Calculate volume: V = a³ = (0.1 m)³ = 0.001 m³
2. Apply density formula: ρ = m/V
3. ρ = 2.4 kg ÷ 0.001 m³ = 2400 kg/m³
Result: The concrete density is 2400 kg/m³ (typical concrete density)

Understanding Cube Density
What is Density?
Density is a fundamental physical property that describes how much mass is contained within a given volume. For cubic objects, this calculation becomes straightforward since the volume can be easily determined from the side length.
Cube Volume Calculations
- •From side length: V = a³
- •From face diagonal: V = (f/√2)³
- •From space diagonal: V = (d/√3)³
Density Formula
ρ = m/V
For cube: ρ = m/a³
- ρ: Density (kg/m³)
- m: Mass (kg)
- V: Volume (m³)
- a: Side length (m)
Unit Conversions
Common units: kg/m³, g/cm³, lb/ft³
Conversion: 1 g/cm³ = 1000 kg/m³
Practical Applications
Construction Testing
Concrete cubes are tested to verify material quality and strength properties in construction projects
Material Identification
Density measurements help identify unknown materials and verify composition in manufacturing
Quality Control
Regular density checks ensure consistent product quality in manufacturing processes
💡 Practical Tips
- • Always use consistent units throughout your calculations
- • For irregular cubes, measure multiple dimensions and use the average
- • Consider temperature effects - most materials expand when heated
- • Porosity can significantly affect density measurements in materials like concrete
