Question Analysis:
This question involves calculating the lateral surface area of a cube.
The main focus is on identifying the correct faces and applying the formula.

Key Concept Explanation:
A cube has 6 identical square faces.
Lateral Surface Area (LSA) includes only the side faces (4 faces), not the top and bottom.
Formula: LSA = 4 × (side length)².

Step-by-Step Solution:
Given: Side length = 5 cm.
Area of one face = 5 × 5 = 25 cm².
LSA = 4 × 25 = 100 cm².
