Cube Volume Calculator
Calculate the volume of a cube from its side length. A cube is a three-dimensional shape with six equal square faces. Volume = side³.
Formula
V = s³; SA = 6s²; Face Area = s²; Space Diagonal = s√3
- A cube has 6 faces, 8 vertices, and 12 edges
- All faces are identical squares
- Space diagonal connects two opposite vertices through the cube's interior
- Results are exact for the given side length
Cube Volume Example
Inputs
- Side Length: 5 cm
A cube with side 5 cm: Volume = 5³ = 125 cm³; Surface Area = 6 × 5² = 150 cm²; Space Diagonal = 5√3 ≈ 8.66 cm.
Frequently asked questions
What is cube volume?
Cube volume is the amount of space inside a cube, calculated as V = s³, where s is the side length.
What is the difference between volume and surface area?
Volume (V = s³) measures space inside; Surface Area (SA = 6s²) measures the total area of all 6 faces.
What is the space diagonal?
The space diagonal runs from one vertex to the opposite vertex through the cube's interior, with length s√3.
How do I find the side length if I know the volume?
Take the cube root: s = ³√V. For example, if V = 125, then s = ³√125 = 5.
