The bottom of the cube is a 2. This is inferred based on 3 pieces of evidence: 1) Only even numbered sides are dark colored, and 2 is the only remaining even number that is not visible. 2) There are 3 light colored sides and 2 dark colored sides, following the pattern of an equal number of each. 3) The opposite sides that are visible add up to 7, and with the top being 5, the bottom would need to be a 2 to complete the pattern.

My Conclusion:
My claim: (inference) is in red. Evidence in black. Reasoning in blue.
The bottom of the cube is a 2 that is dark. I noticed that only even
numbered sides are dark. I observed 3 light colored sides and 2 dark
colored sides. So, if the number is even, it should be dark. That would
also make it an equal number of dark and light numbers. Also, I
noticed the pattern that there were all numbers 1-6, except 2 and that
opposite sides added up to 7. If the top is 5, then the bottom would
have to be a two to add up to seven.
It’s a cube, 6 faces
5 is on top. The cube says top
Numbers 1,3, 4, 5, and 6 are visible
1, 3, and 5 are light colored
Numbers 4 and 6 are dark colored
All numbers that are light are odd
All numbers that are dark or even.
Opposite sides that I see add up to 7
4 + 3 = 7
1 + 6 = 7

2 sides are dark and 3 sides are light.
