A brick weighs more than a sponge because its material, such as clay or concrete, is denser and more compact than the material of a sponge, which is porous and lightweight. The density of the brick's material causes it to have more mass packed into the same volume compared to the sponge.
The answer is they all weigh the same amount are equal in weight which is different then density
A brick made of lead would weigh more than a brick made of iron of the same size. This is because lead is denser than iron, meaning it has more mass packed into a similar volume.
Well it doesn't weigh 10 lbs! Ordinarily, a brick would be considered incompressible, and that is still probable in 5000 ft of water. And assuming that it had no entrained air! BUT, water at 5000 ft is compressible (for which you'll have to look up an hydrology table) and the volume of water displaced by the brick will now weigh more than that volume would have had at the surface. And as soon as you have immersed your brick, it will weigh less than it previously did, by the weight of water it displaced. remember Archimedes? SO your brick would now be slightly more buoyant (weigh less) than it did close to the surface. In an exam answer, one would usually say 'assuming the brick is incompressible', and 'assume the brick is impermeable'. Of course you could also 'assume that water is incompressible', and eliminate the hydrology tables! Then proceed with the answer.
Both the 100 pound brick and the 100 pounds of paper weigh the same, as they both have a weight of 100 pounds. The weight of an object is not affected by its volume or density.
The weight of a cube of brick will vary depending on the size and density of the brick. On average, a standard brick weighs approximately 4.5 pounds. You can calculate the weight of a cube of brick by multiplying the weight of a single brick by the number of bricks in the cube.
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
The answer is they all weigh the same amount are equal in weight which is different then density

The same amount as 510mg of brick. 510mg.
That doesn't make sense; a volume by itself doesn't weigh anything, unless you put something inside that volume.

A brick weighs about 3.5 to 9lbs.
Half a pound.
Both the 100 pound brick and the 100 pounds of paper weigh the same, as they both have a weight of 100 pounds. The weight of an object is not affected by its volume or density.
If a brick weighs 1 lb, then half a brick would weigh 0.5 lb. Therefore, 1 and a half bricks would weigh 1 lb (for the full brick) + 0.5 lb (for the half brick) + 1 lb (for the additional brick) = 2.5 lbs.
