A cube, explained.
A cube is a solid with six congruent square faces, twelve equal edges and eight vertices. Three mutually perpendicular edges meet at each vertex. One edge length determines its entire metric geometry.

More than a formula.
A cube is one of the five Platonic solids.
A face diagonal and a space diagonal are different measurements. Surface area is not measured in cubic units.
Explore three geometry facts ↗These tools use ideal Euclidean geometry. Every input must use the same unit. Numerical results are rounded and do not replace measurement, specialist design or safety checks. See worked examples.
