E Correct answer
Explanation

The surface area of a cube is calculated as 6 * (edge length)^2. With an edge length of 5 cm, the area is 6 * 25 = 150 square cm.

AI explanation

The surface area of a cube is calculated using the formula S = 6 * a^2, where a is the length of an edge. Substituting the given edge length of 5 cm into the formula gives 6 * 5^2 = 6 * 25. The total surface area is 150 square cm.
