Surface Area of a Cube Calculator
Surface Area of a Cube. Example: Edge length: 2 gives 24 m². A closed cube with six equal square faces: enter edge length in meters from 0.001 to 1,000,000 m. Result is total outer surface area, not one-face area or volume. Open-top boxes, thickness and material waste are excluded.
How the calculation works
6 × edge²
Worked example
With edge length 1 m, area is 6 m².
Assumptions and limits
A closed cube with six equal square faces: enter edge length in meters from 0.001 to 1,000,000 m. Result is total outer surface area, not one-face area or volume. Open-top boxes, thickness and material waste are excluded.
