The LSA (lateral surface area) of a cube of side 1 cm is

• (1) 16 cm²
• (2) 4 cm²
• (3) 2 cm²
• (4) 1 cm²

The lateral surface area (LSA) of a cube refers to the area of the sides of the cube, excluding the top and bottom faces. For a cube with a side length of 1 cm, the formula to calculate the LSA is:

Formula for Lateral Surface Area

The formula is given by:

LSA = 4 × (side length)²

Calculation Steps

• Substituting the side length: LSA = 4 × (1 cm)²
• Calculating: LSA = 4 × 1 cm²
• Result: LSA = 4 cm²

Thus, the lateral surface area of a cube with a side length of 1 cm is 4 cm². Therefore, the correct answer is (2) 4 cm².
