"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
3 X 10^3
Density = mass/volume = 27/3 = 9 grams per millilitre.
Density is 30 g/cm3
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.
Because the density of the egg is higher than the density of tap water, so it sinks. Density (ρ), as shown below in Equation 1, is the mass (m) of a material per unit volume (v). For example, the density of freshwater under standard conditions is approximately 1 gram (g) per cubic centimeter (cm3). In other words, if you filled a 1-cm x 1-cm x 1-cm box with freshwater, the water inside the box would have a mass of 1 g. Adding salt to the water increases the density of the water, because the salt increases the mass without changing the volume very much. With enough added salt, the saltwater solution density is higher than the egg's, and the egg will then float.Equation 1:mρ =vρ = Density in whatever units are used for mass and volume.m = Mass in grams (g), kilograms (kg), or any other unit of weight.v = Volume in centimeters cubed (cm3), meters cubed (m3), or any other unit of volume.
Problem: You are given two unknown liquids. Find the density of each. Materials: 100ml graduated cylinder, triple beam balance, calculator, 2 unknown liquids. Procedure: 1) Find the mass of the empty graduated cylinder. 2) Pour unknown liquid #1 into the graduated cylinder to the 50 ml. level. 3) Find the mass of the graduated cylinder with 50ml of unknown liquid #1. 4) Repeat steps 1-3 for unknown liquid #2. We can calculate density of a liquid using the formula: Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder). Now let's calculate the densities of the two liquids using the following given data. Liquid #1: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #1= 128 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid=_____ c) Density of liquid #1 =____ Liquid #2: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #2= 117.5 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid =_____ c) Density of liquid #2=____ Check your answers by inserting the value in the box below.
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.
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.
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.
0.75 g/cubic cm--12/23/10 Update:The formula for density is:D=m/v ("Density equals mass divided by volume." This is why we get an answer in mass units over volume units--it expresses the amount of matter in a given space (e.g. "grams per cubic centimeter").--Julian B.
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.
Get a sample of the metal. Use a scale to find its mass. If it is shape is that of a rectangular solid (box) measure length, width, and height and multiply to find volume. If it is irregularly shaped, use the water displacement method to find its volume. Divide the mass by the volume to get the density.
The density of the solid is about 0.86 g/cm3
