Question

A cube is to be coloured in such a way as to avoid the same colour on adjacent surfaces. What is the minimum number of colours you will require ?

• A. Four
• B. Three
• C. Six
• D. Nine

Answer 1

The Correct Option is B

The correct option is (B): Three
Explanation To color a cube such that no two adjacent faces share the same color, you can achieve this with a minimum of three colors. This is because a cube can be thought of as a planar graph, and according to the four color theorem, three colors are sufficient for the cube as each face can be colored in a way that no two adjacent faces have the same color.
