A 10 kg box is sitting on a horizontal tabletop. The box is a rectangular solid whose surfaces have areas of 100 cm, 150 cm, and 200 cm2. The coefficient of static friction between all surfaces of the box and the tabletop is 0.4. If a horizontal force is to be applied to slide the box, on which surface should the box be lying against the tabletop to make sliding the box easiest?

a. It does not matter which surface is in contact with the tabletop.
b. The 150 cm^2 surface.
c. The 100 cm^2 surface.
d. The 200 cm^2 surface.
