It is a 40 litre capacity, most probably a couple of litres bigger as it is a Size 3 which is the longest back length (a few models have a size 4 which is longer still). I find it comfortable at 180cm tall. I expect you will be at the lower end of the fitting range but a quick measure can sort that out. Scratching around in older web pages I found a retail site that stated the AMP 40 (original not the V2) using the normal back length measure from the C7 vertebra to the iliac crest size 3 fits 42-49cm. If you are unfamiliar with this measurement a google will find any number of diagrams and notes on working this out.
It is frameless but the back is reasonably padded and seems to have a flexible back board in it. I have used the pack for a 7 day trip on the olt carrying at least 12 kg as I had food for two and a heavier than normal tent - was still comfortable.
