The best number that describes the location of the basement woodshop is -15.6 feet or negative 15.6 feet.
To determine the best description of the location of the basement woodshop, we need to calculate the total vertical distance from ground level to the woodshop.
Given that Arthur's room is 24.3 feet above ground and he descends 39.9 feet to the basement, we can add these two distances together:
24.3 + 39.9 = 64.2 feet
Therefore, the best description of the location of the basement woodshop is 64.2 feet.
