Question

find the surface area of the prism using the net. what is the total surface area? front and back triangles: 64 cm² side rectangles: 72 cm² bottom rectangle: 32 cm² surface area: ? cm²

Explanation:

Step1: Identify surface - area components

The surface area of the prism is the sum of the areas of its faces.

Step2: Add the given areas

We are given the area of the front - and - back triangles ($64\ cm^{2}$), side rectangles ($72\ cm^{2}$), and bottom rectangle ($32\ cm^{2}$).
The formula for the surface area $SA$ is $SA=64 + 72+32$.
$SA=168\ cm^{2}$

Answer:

$168\ cm^{2}$
