[Blindmath] Question

[winona]

Hello everyone,

I have a geometry exam next week and my teacher told us that we 
can use one sheet of notebook paper front and back for anything 
that we don't feel comfortable with or are a little unsure of.  
So my question is, how many pages is that in Braille? I've heard 
that for every page and Braille is only is only half a page in 
print, but sence geometrry have so much pictures, wouldn't that 
take up more space than words?

I hope this makes sence.  And I have to do it because my teacher 
is grading it as a quiz grade.

Thanks,
Winona
