My suggestion would be to fill containers with variables of whatever kind you are interested in, and use system monitoring tools to see how much memoryu your process consumes. When I did some exrcises testing for memory usage, for instance, the readings indicates that empty anonymous hashes could take about 60-70 bytes apiece. This ballpark figure was good enough for me. It may be that, by perusing perldoc perlguts you can garner sufficiient information to precisely calculate what the memory cost of any scalar or container is.
