Side Length (s) units
Cube Formulas

Volume:

$V = s³$

Surface Area:

$SA = 6s²$

Face Diagonal:

$d_f = s√2$

Space Diagonal:

$d_s = s√3$

Where $s$ is the side length of the cube.

Example:

For a cube with side length 4 units:

  • Volume = 4³ = 64 cubic units
  • Surface Area = 6 × 4² = 96 square units
  • Face Diagonal = 4√2 ≈ 5.66 units
  • Space Diagonal = 4√3 ≈ 6.93 units
