To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6 \cdot s^2 \]
where \(s\) is the length of an edge of the cube.
Given that the edge length \(s\) is 5 inches, we can substitute this value into the formula:
\[ \text{Surface Area} = 6 \cdot (5 , \text{in})^2 \]
Calculating \( (5 , \text{in})^2 \):
\[ (5 , \text{in})^2 = 25 , \text{in}^2 \]
Now multiply by 6:
\[ \text{Surface Area} = 6 \cdot 25 , \text{in}^2 = 150 , \text{in}^2 \]
Thus, the surface area of the cube is 150 in².
