Use this cube diagonal calculator to calculate the space diagonal of a cube by entering the edge length. Apply the cube space diagonal formula for precise results.
a = edge length
Multiply the edge length by √3 to find the space diagonal of a cube.
| a | Diagonal |
|---|---|
| 2 | 3.464102 |
| 3 | 5.196152 |
| 4 | 6.928203 |
| 5 | 8.660254 |
| 6 | 10.392305 |
1. Take the edge length (a).
2. Multiply it by the square root of 3 (√3).
3. The result is the cube's space diagonal.
This cube diagonal calculator automatically computes the space diagonal using the cube space diagonal formula with up to six decimal places.
• A cube has 12 edges and 8 vertices.
• The space diagonal is longer than the face diagonal.
• Cube diagonals are used in 3D geometry and design.
• Calculating the space diagonal helps in packing and engineering.
• The formula involves the square root of 3 for accuracy.
