1. What is a Density Calculator?

Definition: This calculator computes the density of an object using its mass and dimensions (length, width, height).

Purpose: It helps students, engineers, and scientists determine material density for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass of the object (kg)
• \( L \) — Length of the object (m)
• \( W \) — Width of the object (m)
• \( H \) — Height of the object (m)

Explanation: The mass is divided by the volume (L×W×H) to obtain the density.

3. Importance of Density Calculation

Details: Density is a fundamental material property used in material identification, buoyancy calculations, and quality control.

4. Using the Calculator

Tips: Enter the mass in kilograms and all dimensions in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses kg for mass and meters for dimensions, resulting in kg/m³ density units.

Q2: Can I use different units?
A: Yes, but you'll need to convert your measurements to kg and meters first for accurate results.

Q3: What's a typical density range for common materials?
A: Water is 1000 kg/m³, aluminum ~2700 kg/m³, steel ~7850 kg/m³, wood typically 300-900 kg/m³.

Q4: Does this work for irregular shapes?
A: No, this calculator is for regular rectangular shapes. For irregular shapes, use water displacement methods.

Q5: How precise should my measurements be?
A: Use the most precise measurements available, as small errors in dimensions can significantly affect density calculations.
