The surface area of a cube is calculated by the formula: 6 * (edge length)^2.

Step 1: Identify the edge length of the cube. In this case, it is given as 7 cm.

Step 2: Substitute the edge length into the formula. So, Surface Area = 6 * (7 cm)^2.

Step 3: Calculate the square of the edge length. (7 cm)^2 = 49 cm².

Step 4: Multiply the result by 6. 6 * 49 cm² = 294 cm².

So, the total surface area of the cube is 294 cm². Therefore, the correct answer is 294 cm².
