Question

follow the steps to find the surface area of the rectangular prism. what is the total surface area? top and bottom: 360 cm² front and back: 72 cm² sides: 90 cm² total sa: ?

Explanation:

Step1: Recall surface - area formula for prism

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

Step2: Add the given areas

We add the area of the top - and bottom, front - and back, and sides. So, $SA=360 + 72+90$.

Step3: Calculate the sum

$360+72 + 90=522$ $cm^{2}$.

Answer:

$522$ $cm^{2}$
