To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the length of a side of the cube.
Given that the side length \( s = 8 \) cm:
\[ \text{Surface Area} = 6 \times (8, \text{cm})^2 = 6 \times 64, \text{cm}^2 = 384, \text{cm}^2 \]
So, the surface area of the cube is 384 cm².
