Identify the formula for the surface area of a cube: \(SA = 6 \times a^2\), where \(a\) is the length of one side of the cube.
Identify the formula for the volume of a cube: \(V = a^3\), where \(a\) is the length of one side of the cube.
Substitute the given side length \(a = 3\) nm into the surface area formula: \(SA = 6 \times (3\, \text{nm})^2\).
Substitute the given side length \(a = 3\) nm into the volume formula: \(V = (3\, \text{nm})^3\).
Calculate the numerical values for surface area and volume using the substituted expressions to find the correct answer.
