Explanation:

Step1: Recall surface - area formula

The surface - area formula of a cube is $S = 6a^{2}$, where $a$ is the side - length of the cube.

Step2: Substitute the side - length value

Given $a = 18$ cm, substitute it into the formula: $S=6\times(18)^{2}$.

Step3: Calculate the result

First, $(18)^{2}=18\times18 = 324$. Then, $6\times324 = 1944$ square centimeters.

Answer:

1944
