Connelly cuts a solid object in half. What happens to the mass, volume, and density of the object that Connelly cuts? A)The mass and volume are both divided by two, and the density is divided by four. B) The volume is divided by two, but the mass and density do not change. C) The physical properties of the substance change, and all three properties must be remeasured. D) The mass and volume are both divided by two, but the density remains the same.
is it c?

not c.

b?

I think it is D.

Are you guessing?
Think about it.
If you cut a piece of wood in the middle, what happens to the mass of each piece? What happens to the volume of each piece? Now the density of the wood is g/volume. You've changed the grams (to 1/2) and you've changed the volume (TO 1/2), what about the density? 
d?

then its d?

d it is.
