Why are different tones used on different planes of a cube?

Answer and explanation

Correct answer: Light falls at different angles

The governing concept is the relationship between light direction and plane orientation. Each plane of a cube faces the light at a different angle, so it receives a different amount of illumination and is represented with a different value. Therefore, option A is correct. The names of the planes, paper colour, and pencil length do not determine their tones. A consistent light source may make one plane light, another middle-valued, and a turned-away plane darker, clearly describing the cube’s form.
