Question 2

1. Understand the shapes:

   • A square is a flat shape with equal sides.
   • A cube is a box-like solid with 12 straight edges.

2. Count the required parts:

   Number of sides of a square:

   \[ 4 \]

   Number of edges of a cube:

   \[ 12 \]

3. Write the ratio (square : cube):

   \[ 4 : 12 \]

4. Simplify the ratio: divide both numbers by \(4\).

   \[ rac{4}{4} : rac{12}{4} \]

   \[ 1 : 3 \]

5. Final answer:

   \[ oxed{1 : 3} \]

So, the ratio of the number of sides of a square to the number of edges of a cube is 1 : 3.
