Question

Can someone help me with #4?? I think it's 64 but idk how to get to it

Answer 1

3/16 in thick per album
12 inches is max

so

height per record times number of recrds=total height
3/16 times number of records=12
times both sides by 16/3
number of records=192/3
number of records=64

64 records can fit
