Step-by-step
- V = s³ = 5³ = 125.0000.
- Surface area = 6s² = 6 × 25 = 150.0000.
- Body diagonal = s√3 = 8.6603.
How to use this calculator
- Enter edge length.
- Read volume + surface area.
About this calculator
A cube has six identical square faces and twelve equal edges. Volume V = s³. Surface area = 6s². Body diagonal (corner to opposite corner through interior) = s√3. Doubling the edge multiplies volume by 8 (cube law): the basis of cube-square problems in physics and biology.
Frequently asked
V = s × s × s (3D). Area = s × s (2D). Volume scales faster — cube of size 10 has 1000× the volume of size 1, but only 100× the area.
