1. What is Space Diagonal of Cube?

The space diagonal of a cube is the longest straight line that can be drawn inside the cube, connecting two opposite vertices. It passes through the center of the cube and is the three-dimensional equivalent of the face diagonal.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sqrt{3} \) — Square root of 3 (approximately 1.732)
• Inscribed Cylinder Radius — Radius of the largest cylinder that fits inside the cube

Explanation: The formula relates the space diagonal of a cube to the radius of the inscribed cylinder, utilizing the mathematical relationship between these geometric properties.

3. Importance of Space Diagonal Calculation

Details: Calculating the space diagonal is important in geometry, architecture, and engineering for determining maximum distances within cubic structures, packaging design, and spatial analysis.

4. Using the Calculator

Tips: Enter the inscribed cylinder radius in meters. The value must be positive and greater than zero for accurate calculation.
