| To solve this problem, remember that the surface area of a cube is equal to the sum of the areas of its six faces. Since the face of a cube is a square, let’s calculate the area. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. Knowing that the side of the square is 7 centimeters, we calculate the area of one face.

S = 7 * 7 = 49 cm ^ 2.

Let’s calculate the area of the entire surface.

S half top = 49 * 6 = 294 cm ^ 2.

Answer: 294 cm ^ 2.
