How to Calculate Cube

What is Cube?

A cube is a regular hexahedron — a 3D shape with 6 equal square faces, 12 edges, and 8 vertices. All edges are the same length. It is the simplest and most symmetric polyhedron.

Step-by-Step Guide

  1. 1Volume = side³
  2. 2Surface area = 6 × side²
  3. 3Face diagonal = side × √2 · Space diagonal = side × √3

Worked Examples

Input
s = 5
Result
V=125, SA=150, diagonal=8.66
SA=6×25=150
Input
s = 10
Result
V=1000, SA=600, diagonal=17.32
Space diagonal=10√3
