Density = mass/volume
density = 6/2
density =3g/cm3
Density = mass/volume. 12.9g/15cm3 = 0.89g/cm3.
Density = mass/volume = 27/3 = 9 grams per millilitre.
"125 cm" is not a volume. Let's assume "cm" was a typo, and "cm3" was intended. density = (mass) divided by (volume) = (5/125) = 0.04 gm/cm3
Density is 30 g/cm3
Your question does not make sense. 200 cubic centimetres is not a measure of mass. Do you mean 200 grams? To find density you divide the mass by the volume.

You can't. centmetres are units of length, and kilograms are units of mass. If you know the density of the box, in grams per millilitre, multiplying the length by height by depth of the box in centimetres will give the volume in millilitres. Multiplying the density by the volume will give the mass in grams.
A box with high density will have more mass packed into the same volume compared to a box with low density. This means that the high-density box will be heavier and contain more material in the same space as the low-density box.
Density is defined as mass per unit volume. 432/200 gives the density of 2.16 gms/cc. Which happens to be the density of common salt, sodium chloride. Note that to get the density of a salt, the salt in the box has to be a solid lump not a powder which would have a lower density.
The literal, direct answer to the question, as stated, is: Push!If you mean "How do you convert a quantity of mass into the quantity of volume ?",then the answer is: You don't. The same mass of different substances has differentvolumes, so they don't convert.If somebody tells you the mass of something he has in a box, and asks you tocalculate its volume, you must ask him for its 'density'. If he can't answer you,then simply bid him good day. If he does tell you the density, then divide themass by the density, and you will then know the volume, to share with himor not, as you choose.
From what you have learned about density, you can infer that the small box with greater weight is likely more dense because it contains more mass within its volume. Conversely, the large box with less weight is likely less dense as it contains less mass in a larger volume. Density is a measure of how much mass is contained within a given volume, so a heavier object of the same volume is denser.
To float in olive oil the box needs to displace a volume of olive oil that has the same mass as the box - the less dense the oil (for example by being warmer) the more volume the box will need to displace to equal its mass. If it cannot displace a volume of olive oil that equals its mass, the box will sink. Or to put it another way, the box will float in olive oil as long as its density is less than that of the oil.
