To find the surface area of a cube when the side length \( s \) is 10 cm, we use the formula for the surface area of a cube:
\[ \text{Surface Area} = 6s^2 \]
Substituting \( s = 10 \) into the formula:
\[ \text{Surface Area} = 6(10)^2 \]
Calculating \( (10)^2 \):
\[ (10)^2 = 100 \]
Now, substituting back into the equation:
\[ \text{Surface Area} = 6 \times 100 = 600 \]
Therefore, the surface area of the cube is:
\[ \text{Surface Area} = 600 , \text{cm}^2 \]
So the answer is \( 600 , \text{cm}^2 \).
