Regular Tetrahedron Calculator
Edge Length (a)
A regular tetrahedron is one of the five Platonic solids, consisting of four equilateral triangular faces. It is the simplest and most symmetric 3D shape with flat faces.
- 1Volume = a³/(6√2)
- 2Surface area = √3 × a²
- 3Height h = a√(2/3)
- 4Edge length a determines all dimensions
Edge a = 6=Volume ≈ 25.46, SA ≈ 62.35
Edge a = 4=Volume ≈ 7.54, SA ≈ 27.71
| Edge a | Volume | Surface Area | Height |
|---|---|---|---|
| 2 | 0.94 | 6.93 | 1.63 |
| 4 | 7.54 | 27.71 | 3.27 |
| 6 | 25.46 | 62.35 | 4.90 |
