Question

Find the surface area of the prism below. Please see the attachment and a. 108cm ^2 is incorrect. Thanks!

Answer 1

Answer: OPTION B

Explanation:

To solve this problem you must add the areas of each rectangle that form the prism;

The area of a rectangle can be calculated with the formula:

`SA=length*width`

There are three pairs of equal rectangles, then you can find the surface area of 3 rectangles and multiply each one by 2, then you obtain that the surface area of the prism is:

`SA_(prism)=2(6cm*2cm)+2(3cm*6cm)+2(3cm*2cm)=72cm^(2)`
