A sawmill runs for three 4-hour shift per day. it produce 500 2x4's per hour, which are divided into 50 piece bundles automatically. if a forklift is able to load 10 bundles of 2x4 per hour, how much hour will it take the operator to load a full day production

Since the factory runs for three 4 hours shift per day, that many total full day work hours is 12 hours.

Now, the factory produces 50 bundles per hour, and the operator loads the forklift 10 bundles per hour, the operator will need 60 hours to load a full day production.

The formula is 12 x 50 / 10 = 60
