Cube Volume and Surface Area Calculator
Enter a positive side length to calculate V = s³ and S = 6s² locally.
A QUICK WALKTHROUGH
How to use this tool
- Enter the cube side length.
- Optionally add a unit label.
- Calculate and copy the volume and surface area.
Cube formulas
For side length s, volume is s³ and total surface area is 6s². The input must be finite and greater than zero.
Units and precision
Use one length unit. Results use its squared and cubed forms and are rounded to 12 significant digits for display.
GOOD TO KNOW
Common questions
