group form fields into blocks

Is it possible to make a repeating block with 10 intputs in a jotform and then calculate how many blocks have rotated on the form?

Can group of fields be shoved into some kind of container

My understanding is that you would like to group form fields into sections. Is that correct? If so, you can use the SECTION COLLAPSE field to group them into blocks. Here's an example:

Also, a Configurable List widget can be used for this as well, however, I cannot recommend it since you mentioned you'll be using the fields for calculations - which is not possible for the said widget.

calculate how many blocks have rotated on the form?

I'm actually not quite sure about this one. But if you mean you would like to calculate the values added on the fields within those sections, you can add a FORM CALCULATION widget at the bottom of the form, then add the necessary fields there. Here's another example:
