Is there any option to view memory used by the project?

There is no option to view the space used per project, but in the organization settings page you see the space used for ALL your projects.

Thanks for your immediate response.As you mentioned, i didn't see any option in 'organization settings' to view memory consumption. Is this only for paid version ? If not then please let me know the clear steps to find out the memory consumption please.

Sorry - I meant in the "Billing" page, that's where it's shown

i got it now.Thank you.
