It makes more sense if you think about it in numerical terms.
Say if there were 10 eggs per carton and there were 5 cartons, what would you do to find the total?
You would multiply them
It is the same in this case
The expression would be n x k
It can be written as just nk though

Answer:
The surface area of the prism is <u>480 in²</u>.
Step-by-step explanation:
Given:
The prism dimensions are 8in 15in 17in and 9in.
Now, to find the surface area:
So, to get the surface area we put formula:
a=8in, b=15in, c=17in and h=9in.
Surface area = 2A+(a+b+c)h.
Whereas, 
And, 
<em>Now, we find </em><u><em>s</em></u><em> first:</em>
<em>Then, we get</em><u><em> A </em></u><em>:</em>
<em>On solving we get:</em>
Now, putting the value of A in the formula to get the surface area:
Therefore, the surface area of the prism is 480 in².
D
You need to use trigonometry, and square all of the numbers, you then add the lowest two and they should sum to the other number.
The set that this works for is the correct set.
Hope this helps x
