The image shows 12 aluminum cylinders, different sizes. Which statement below is correct?

• They all have the same mass and same volume

• Because they are all the same material, they all have the same density.

• They all have different densities. The larger the cylinder, the greater the density.

The image shows a block of wood cut in half. Select all true statements each new piece.  

• Because they are half the mass and volume of the original block, each new piece is half the density.

• Because they are all the same material, each cut piece is the same density as the original block.
