Cube Formulas
1. Volume

A cube's volume is found by multiplying its edge length by itself three times (cubing it).

V = s³
2. Surface Area

A cube has 6 identical square faces. Find the area of one face (s²) and multiply by 6.

A = 6 × s²
3. Space Diagonal

The distance from one corner through the inside of the cube to the opposite corner.

d = s × √3
