Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
Bricks have more density whereas feathers have less comparatively. Space occupied ie volume = mass/ density. So space occupied is inversely related to the density. Hence feathers occupy more space than the bricks.
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 pound of feathers because feathers are less dense than lead and therefore take up more volume for the same mass.
A ton of brings does not exist, but if you mean a ton of bricks or a ton of feathers, they both weigh the same - 2000lbs. A ton is an imperial unit of measuring weight - it doesn't measure volume (or space that on object takes up). A ton of bricks would be relatively compact, while a ton of feathers would take up an enormous amount of space.
5000 lbs of sand, give or take a hundred.
because sand is smaller than feathers and it would take up as much space with the sand , and if the feathers were there it would take up more space because its and larger object than the sand .
i dont know if this is correct butt, i think mass, because , mass is considered as matter half the time, and a feathers kilograms take up less space than sands. this is because of the width of the object or substance? no promises but i think this is rightt <333

A pound of feathers has more mass. The are lighter so they would take up more space to make a pound.
the densities are different
It takes alot more feathers to equal a kilogram than it does bricks

In space robots can take pictures and videos they can also grab samples of sand, rocks, and plants.

Small dogs take less space and need less space to exercise.
It depends on the duration of space travel. If the duration is less, you have to take less stuff.
