Explanation:

Step1: Identify dimensions

Let the length $l = 10$ cm, width $w=9$ cm and height $h = 8$ cm.

Step2: Find area of front - back

The area of the front and back of a rectangular prism is given by $2\times (h\times l)$. Substitute $h = 8$ cm and $l=10$ cm.
$2\times(8\times10)=2\times80 = 160$ $cm^{2}$

Answer:

$160$ $cm^{2}$
