TM, this brings back a horrible memory from last year, when easy child had to do a project about "What Love Means To You". A heart-shaped booklet with a sentiment on each page (and yes, a neatly coloured picture to go with each sentiment). Aside from nearly dying from the syrupy-ness, I did wonder what the children were learning from it all other than Homework is Tedious and Useless. I am eternally grateful that easy child's new school does not assign homework.
And yes, to your original question, about 17 or 18 hours. One hour per page, plus another hour for "finishing".
Honestly, the only thing I ever learned from homework during my semi-difficult child years was how to not do any homework, wear down my teachers, and get them to stop assigning it to me or punishing me for not doing it.
I'm with Sheila.
