Cal State application question

One of the questions is
What was the average number of hours worked per week over the most recent 36 months?
I dont have a job where they pay me a salary but my family sells furniture from our home on offer up and it’s still a lot of work to carry every dresser, bed, mattress, etc. so I was wondering if I could add those hours as work hours or not since its not a salary thats recorded on taxes and stuff?
