[b]p6.[/b] A family of funny dwarfs consists of a dad, a mom, and a child. Their names are: $A$, $R$, and $C$ (not in order). During lunch, $C$ made the statements: “$R$ and $A$ have different genders” and “$R$ and $A$ are my parents”, and $A$ made the statements “I am $C$'s dad” and “I am $R$'s daughter.” In fact, each dwarf told truth once and told a lie once. What is the name of the dad, what is the name of the child, and is the child a son or a daughter?

### Problem 1:
To every face of a given cube, a new cube of the same size is glued. The resulting solid has how many faces?

1. A cube has 6 faces.
2. When a new cube is glued to each face of the original cube, each new cube shares one face with the original cube.
3. Therefore, each new cube contributes 5 new faces (since one face is shared and thus not visible).
4. There are 6 new cubes, so the total number of new faces is \(6 \times 5 = 30\).
5. Adding the original 6 faces of the cube, we get \(30 + 6 = 36\).

The final answer is \(\boxed{A \text{ is the dad, R is the mom, and C is the son}}\).
