How it works
A cube is the simplest solid: one side length s determines everything. Its volume is s³ — length × width × height with all three equal — and its surface area is 6·s², six identical square faces. The powers matter. Doubling the side multiplies the surface by 4 but the volume by 8; this cube-square law governs why big ice blocks melt slower, why packaging costs grow slower than contents, and why small creatures dominate the insect world. A handy metric anchor: a cube of side 10 cm holds exactly one litre (1,000 cm³), and a cube of side 1 m holds 1,000 litres — one cubic metre. That makes this calculator a quick capacity check for boxes, tanks and containers.

Frequently asked questions
How do I find a cube’s volume?
Raise the side length to the power of three — side × side × side.
What is the surface area?
Six identical square faces, so 6 × side² in square units.
How do I convert the volume into litres?
Compute in decimetres: side 1 dm (10 cm) gives exactly 1 litre. In general, litres = cm³ ÷ 1000, and 1 m³ = 1,000 litres.
