B Correct answer
Explanation

Lateral surface area of a cube = 4 * side^2. With side = 8, LSA = 4 * 64 = 256 cm^2.

AI explanation

The lateral surface area of a cube is the area of its four vertical faces, calculated as $4s^2$. Substituting the side length gives $4 \times 8^2 = 4 \times 64 = 256$. The lateral surface area is 256 cm squared.
