Blocking saves space?

Hi Moderators,
I'm not sure if I'm posting this topic under right topic . Sorry if I'm not.
Hi All,
I found below in publib
FB (Fixed Blocked)
This format designation means that several logical records are combined into one physical block. This format can provide efficient space utilization and operation. This format is commonly used for fixed-length records.
I knew that blocking improves performance by reducing the time required to read and write a DASD file. But I couldn't understand how blocking helps in space utilization. Can someone please help me to understand this?
Thank you in advance!
