Answer: 36 inches
Explanation:
The lateral surface area of a cube with sides of length 3 inches is given by the sum of the areas of all four side faces. Each side face is a square with an area equal to the product of the length and width, which in this case is 3 inches by 3 inches. Therefore, the lateral surface area of the cube is:
LSA = 4 x (3 inches x 3 inches) = 36 square inches
So the lateral surface area of the cube is 36 square inches
