False. If the area is 0 that means there is nothing there, therefore the area of a polygon cannot be zero.
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).

They estimated it by the last digit in 68,658. Since 8 is over 5, you round it up to 70,000. Another way to put it is that 68,658 is closer to 70,000 than it is to 68,000. Does that make sense?
