Calculate the volume of a cube instantly with this free interactive 3D calculator. The formula is V = a³, where a is the length of any edge. Since all edges of a cube are equal, you only need one measurement. Enter the side length in the panel and watch the 3D model scale in real time — volume, surface area, and space diagonal are computed as you type.

Use this tool for real-world calculations: find the volume of dice, storage cubes, cubic containers, ice cubes, or any object with equal length, width, and height. For example, a cube with side length 4 cm has a volume of 64 cm³. The calculator also shows the surface area (6a²) and space diagonal (a√3).
