Cube Calculator
Volume and surface area of a cube from its side length.
Worth Knowing
A cube's simplicity makes it a useful lens on how dimensions scale: double the side and the surface area quadruples while the volume grows eightfold. This 'square-cube law' has real consequences — it's why a scaled-up structure needs proportionally thicker supports and why finely diced food cooks faster, since cutting increases surface area relative to volume. All six faces are identical squares, so both formulas reduce to neat powers of a single side length.
