Answer:
4:1
Step-by-step explanation:
We have an equation for the surface area of a rectangular prism:
A= 2 (w*l+ l*h+ h*w)
Plug l= 16 in, w= 12 in, and h= 5 in into the above equation, we have:
A= 2 (12 in*16 in+ 16 in* 5 in+ 5 in* 12 in)= 664 in^(2).
The final answer is 664 in^(2).
Hope this is helpful~
