Question

follow the steps to find the surface area of the rectangular prism. what is the area of the top and bottom? top and bottom: ? front and back: sides total sa 3 cm 9 cm 9 cm

Explanation:

Step1: Recall area formula for rectangle

The area of a rectangle is $A = l\times w$. For the top - and bottom of the rectangular prism, the length $l = 9$ cm and the width $w = 9$ cm.

Step2: Calculate area of top and bottom

Since the top and bottom are congruent rectangles, the combined area of the top and bottom is $2\times l\times w$. Substitute $l = 9$ cm and $w = 9$ cm into the formula: $2\times9\times9=162$ $cm^{2}$.

Answer:

$162$ $cm^{2}$
