10,368 You will ignore the 36 animals in one bag. That number isn't necessary. Ok So you know that one bag weighs 12oz. and 48 bags are in one box. There are 18 boxes in 1 crate so... you are going to do it this way.
12 x 48= 576
576 x 18 = 10,368oz in one crate
so that is your answer.
Hope it is correct.
