1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's an important characteristic property of materials and is used to identify substances and determine buoyancy.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass of the object (kg)
• \( l \) — Length of the cube (m)
• \( w \) — Width of the cube (m)
• \( h \) — Height of the cube (m)

Explanation: The formula calculates how much mass is contained in a given volume, which defines the material's density.

3. Importance of Density Calculation

Details: Density calculations are essential in physics, engineering, and materials science for identifying substances, designing objects, and understanding buoyancy and flotation.

4. Using the Calculator

Tips: Enter mass in kilograms and dimensions in meters. All values must be positive numbers. The default values calculate the density of a 12 kg cube with 0.2m sides.

5. Frequently Asked Questions (FAQ)

Q1: What are typical density values?
A: Water has a density of 1000 kg/m³. Metals range from 2700 kg/m³ (aluminum) to 19300 kg/m³ (gold).

Q2: How does temperature affect density?
A: Most materials expand when heated (lower density), except water which is densest at 4°C.

Q3: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units of mass/volume.

Q4: Why is density important in engineering?
A: It affects material selection, structural design, buoyancy, and thermal properties.

Q5: How accurate is this calculation for irregular objects?
A: This calculator assumes perfect cube shape. For irregular objects, volume must be measured differently.
