Question.  2

The ratio of the number of sides of a square to the number of edges of a cube is

(A)

1 : 2

(B)

3 : 2

(C)

4 : 1

(D)

1 : 3

Detailed Answer with Explanation:

  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.
