Julio used cardboard squares as the flat surfaces of a cube. How many squares he use?

Hope this answer helps, it would be 6 since there is 6 sides to a cube.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

How many groups are there?
