What is a number cube?

A number cube, also known as a dice, is a cube with each face marked with a different number from 1 to 6. It is commonly used in games and probability experiments to generate random numbers. The sides of a number cube are usually arranged in such a way that the sum of any two opposite faces is 7. This property ensures that the cube is fair and unbiased when rolled. Number cubes are often used in math education to teach concepts such as probability, statistics, and basic arithmetic operations.
