What is it that you need help with? Is there some question you are trying to answer, or problem you are trying to solve with this information?

1. A publishing project will require a calculation of the book's spine width. The formula reads thusly: "Total page count divided by paper thickness." A more precise mathematical spine width formula is: "page count/2 x paper gram weight x paper volume /1000 - rounded up to nearest whole number."

So a 100-page book using paper which is 80 gsm with a volume of 1.8 would require a spine width of 8 mm. I am trying to figure out how this answer was achieved.

, and 7.2 rounded up is 8.

Just substitute the given quantities into the formula (assuming that the volume is given in the correct units):





If we're rounding to a whole number, we'll need a spine width of 8 mm (7 is closer, but it isn't wide enough).

Thank you so much for your help with this.
