The box is easier to move.
Friction
an object's acceleration depends on the object's mass and the force applied to it. the lager the force applied to it.
Sand. Density is mass / volume. So a higher volume will equal a lower density. Clearly a Kg of feathers will (normally) take up more volume than a Kg of sand therefore the feathers are less dense. You could think of it this way: density is measuring how close together the atoms in a substance are. When the atoms are closer together they take up less volume and the substance is more dense. If you put a Kg of feathers in a box, the feathers would not all join together perfectly meaning that there would be gaps between feathers and therefore the volume taken up by the feathers is greater. You could prove this by trying to push your hand through the feathers. You would be pushing through partly air (which is a mixture of gases and the atoms in a gas are further apart than in a solid) so the task would be easier. It is like comparing pushing your hand through a solid and pushing your hand through solids separated by gas. The latter is easier because there is some "room" for the atoms in the solid to move in to and thus for the feathers to move out of the way of your hand.
A steel bear box is simply a box for placing garbage cans that are bear proof, or at least bear retardent.
It depends on the size of the feathers. They vary greatly in size: from the wing feathers of some birds to the downy feathers of others.
Steel conducts heat relatively well, so a steel box is of limited usefulness in keeping a drink cool. A Styrofoam box works better. Your refrigerator may have a steel shell, but it also has insulation packed between the layers of steel.

Kaiser catches humming birds by shooting them down with his catapult and then collecting their feathers and keeping it in a match box
nothing special happens when you collect 62 feathers, but at 50 feathers you will be able to purchase a special weapon, and with 100 feathers you will get a special cape. make sure to give the feathers to your mother, by placing them in the box in her room.
box jellyfish move so they can hunt
Because each is a pound. If it helps to visualize it, think of a pound of books being a small box and a pound of feathers being a very big box.
