C Correct answer
Explanation

The lateral surface area of a cube is given by 4 * side^2. With side = 3 m, the area is 4 * 3^2 = 4 * 9 = 36 m^2.

AI explanation

The lateral surface area of a cube is calculated using the formula 4a^2, where a is the edge length. Substituting the edge of 3 m gives 4 multiplied by 3 squared. This results in 4 multiplied by 9, giving 36 m2.
