To solve this question, we need to analyze the given information and apply logical reasoning to determine the total number of red faces.
Given Information:
- There are 128 cubes in total.
- There are two schemes for coloring the cubes:
- Scheme 1: 64 cubes have two red adjacent faces, one yellow face, and one blue face on their opposite sides. The rest of the faces are green.
- Scheme 2: 64 cubes have two blue adjacent faces, one red face, and one green face on their opposite sides. The rest of the faces are red.
Analysis:
1. Scheme 1:
- There are 64 cubes with two red adjacent faces. Since each cube has 2 red faces, the total number of red faces in these cubes is 64 x 2 = 128.
2. Scheme 2:
- There are 64 cubes with two blue adjacent faces. Since each cube has 2 blue faces, the total number of blue faces in these cubes is 64 x 2 = 128.
- There are 64 cubes with one red and one green face. Since each cube has 1 red face, the total number of red faces in these cubes is 64 x 1 = 64.
- The rest of the faces in these cubes are red, so the total number of red faces in these cubes is 64 x 2 = 128.
Total Number of Red Faces:
To find the total number of red faces, we need to add the red faces from both schemes:
Red faces from Scheme 1: 128
Red faces from Scheme 2: 64 + 128 = 192
Therefore, the total number of red faces is 128 + 192 = 320.
Conclusion:
The correct answer is option 'C', 320. There are a total of 320 red faces in the 128 cubes.

The correct answer is option 'C', 320. There are a total of 320 red faces in the 128 cubes.
