Calculate the surface area, volume, and diagonal of a cube using its side length.
Enter the side length, select a unit, then click Calculate.
A cube is a three-dimensional solid object bounded by six square faces, with three faces meeting at each vertex. All edges of a cube are equal in length. The surface area of a cube is the total area of all six faces, calculated as SA = 6a², where a is the length of one side. The volume is V = a³. The face diagonal (across one face) is a√2, and the space diagonal (through the interior from one vertex to the opposite) is a√3. This calculator is essential for geometry, packaging design, construction, and mathematics education. Understanding cube measurements helps in estimating material requirements, container capacities, and spatial dimensions in real-world applications.
