Explanation:

Step1: Identify surface - area parts

The surface area of a rectangular prism is the sum of the areas of all its faces. We are given the areas of the top - bottom, front - back, and sides.

Step2: Calculate total surface area

Add the areas of the top - bottom ($162\ cm^{2}$), front - back ($54\ cm^{2}$), and sides ($54\ cm^{2}$). So, $SA=162 + 54+54$.
$SA = 270\ cm^{2}$

Answer:

$270\ cm^{2}$
