What is 0.50 kg/L or 0.50 g/mL

There are two blocks on a desk. If the blocks have the same mass, but block 1 has a larger volume than block 2, which block has the greater density?

What is block 2

An empty cube is placed into water and it floats. What are two things you could change in order to make the cube sink?

What is increase the mass and decrease the volume.
