# Understanding the Cubic Formula: Side Length = Cube Root of 216 = 6 cm When dealing with three-dimensional shapes, one of the most frequently encountered calculations is determining the side length of a cube when the volume is known. A simple yet powerful formula in geometry is: > Volume of a cube = side length³ This formula allows us to find how long each edge of a cube is if we know its total volume. One classic example is finding the side length when the volume is 216 cm³.
