Final answer:
When you cut a cube in half, the density and mass of the metal stay the same, while the volume and weight change.
Step-by-step explanation:
When you cut a cube in half, the density and mass of the metal will stay the same. Density is defined as mass divided by volume, and since cutting the cube in half does not change the mass or volume, the density remains constant. However, the volume and weight of the metal will change. Volume is the amount of space occupied by an object, so when you cut the cube in half, the volume is halved as well. Weight, on the other hand, is the force exerted on an object due to gravity, and since weight is directly proportional to mass, cutting the cube in half will reduce the weight by half.
