To find the total surface area of a cube, we can use the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the length of one side of the cube.
For a cube with each side measuring 5 cm, we can substitute \( s = 5 \) cm into the formula:
\[ \text{Surface Area} = 6 \times (5 , \text{cm})^2 \]
Calculating \( (5 , \text{cm})^2 \):
\[ (5 , \text{cm})^2 = 25 , \text{cm}^2 \]
Now, substituting this back into the surface area formula:
\[ \text{Surface Area} = 6 \times 25 , \text{cm}^2 = 150 , \text{cm}^2 \]
Therefore, the total surface area of the storage bin is \( 150 , \text{cm}^2 \).
