Question

follow the steps to find the surface area of the square prism. what is the total surface area? top and bottom: 48 cm² front and back: 18 cm² sides: 48 cm² total sa: ?

Explanation:

Step1: Identify surface - area parts

The total surface area (SA) of a prism is the sum of the areas of all its faces.

Step2: Add up areas

We are given the area of the top - and bottom ($48\ cm^{2}$), front - and back ($18\ cm^{2}$), and sides ($48\ cm^{2}$).
The total SA = Area of top and bottom+Area of front and back+Area of sides.
SA=$48 + 18+48$
SA = $114\ cm^{2}$

Answer:

$114\ cm^{2}$
