Notes on Transcribing this page (optional)

I hope I did this correctly; I am not sure if some of the letters were Greek. 

Please see instructions for tables and Greek letters before continuing: https://transcription.si.edu/instructions-women-computers-workbooks

It might help to review some of the completed pages to see the correct format.
Some columns have move than one number as the measurement can have 3 numbers.  The details about this are at the end of the instructions linked above.
Fixed table header. All rows need to have 4 columns.  
[[equation]] needs to be replaced with actual text
