To find the Surface Area of a cube, you can follow these steps:

  1. Identify the length of one side of the cube.
    In this case, each side of the cube is 7 cm.

  2. Calculate the area of one face of the cube.
    The area \( A \) of one face (which is a square) is given by the formula:
    \[ A = \text{side} \times \text{side} = \text{side}^2 \]
    So for one side:
    \[ A = 7 , \text{cm} \times 7 , \text{cm} = 49 , \text{cm}^2 \]

  3. Calculate the total surface area of the cube.
    A cube has 6 identical faces, so the total surface area \( SA \) is given by:
    \[ SA = 6 \times A = 6 \times 49 , \text{cm}^2 \]
    \[ SA = 294 , \text{cm}^2 \]

Therefore, the answers are:

  • One side area: 49 cm²
  • Total Surface Area: 294 cm²
