To find the Surface Area of a cube, you can follow these steps:
-
Identify the length of one side of the cube.
In this case, each side of the cube is 7 cm. -
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:
\[ A = 7 , \text{cm} \times 7 , \text{cm} = 49 , \text{cm}^2 \] -
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
