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: Recall surface - area formula

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

Step2: Add up 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 total surface area $S=64 + 72+32$.
$S = 168\ cm^2$.

Answer:

$168\ cm^2$
