Use this rectangular prism diagonal calculator to compute the space diagonal of a prism by entering its length, width, and height. The rectangular prism diagonal formula ensures precise results.
L = length
W = width
H = height
Square each dimension, sum them, and take the square root to find the space diagonal.
| L | W | H | Diagonal (d) |
|---|---|---|---|
| 2 | 3 | 6 | 7.000000 |
| 4 | 4 | 4 | 6.928203 |
| 5 | 2 | 3 | 6.164414 |
| 6 | 3 | 2 | 7.000000 |
| 1 | 1 | 1 | 1.732051 |
1. Square the length, width, and height.
2. Sum the squared values.
3. Take the square root of the sum.
4. The result is the space diagonal of the prism.
This rectangular prism diagonal calculator automatically computes the space diagonal using the rectangular prism diagonal formula with up to six decimal places.
• Space diagonal is the longest line connecting two opposite corners.
• Useful in 3D design and construction.
• Each face diagonal is shorter than the space diagonal.
• Calculated using the Pythagorean theorem in 3D.
• Key in geometry, packaging, and spatial measurements.
