C Correct answer
Explanation

Lateral surface area of a cube = 4 * side^2 = 64, so side^2 = 16, side = 4. Total surface area = 6 * side^2 = 6 * 16 = 96.

AI explanation

The lateral surface area of a cube is 4a^2, where a is the side length. Setting this equal to 64 cm2 gives 4a^2 = 64, meaning a^2 is 16 cm2. The total surface area formula is 6a^2, which equals 6 multiplied by 16, resulting in 96 cm2.
