Density = Mass/Volume = 8/(4*4*1) = 8/8 = 1 gram per cm3
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. The density of water at normal pressure is very slightly less than 1 g/cm3. The substance that you have, with a density of a twentieth of that cannot be water.
-- Use the length of the cube's side to calculate its volume. -- Divide the cube's mass by its volume. The quotient is its density. The density is 6.25 g/cm3 . Now that you know the answer, you can fill in the missing steps, and learn something at the same time. Is that cool or what !
Measure the length of the edge of the cube and multiply this by itself 3 times.Fill a measuring jug with enough water to cover the cube. Measure the level of water. Immerse the cube in the water in jug and measure the level of the water. The difference in level is the volume of the cube.
The density is (32)/(the length of each edge of the cube)3
Density = mass/volumeFor the cube of water having a mass of 1g:Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3.Density = 1g/1cm3 = 1g/cm3For the block of "plasting" having a mass of 4g:Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3.Density = 4g/6cm3 = 0.7g/cm3I will let you decide which has the greatest density.
Calculate its volume. Divide mass by volume to get its density. Compare that to the density of water - assuming you want to figure out whether it will float or sink in water.
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
Density=mass per volume =1g/cm cube density of 170mL water=170g per 170mL =1g/cm cube
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. The density of water at normal pressure is very slightly less than 1 g/cm3. The substance that you have, with a density of a twentieth of that cannot be water.
To calculate the density of any object all you need to do is measure the mass and volume. Density = mass/volumeThe density of ice is less than water(which is why only the top of lakes freeze in the winter). For those that want to find the density while it is floating in water look below: Imagine a cube of ice floating in water. In order for it to float the force of gravity on the ice must equal the force of buoyancy on the ice. The force of buoyancy as described by Archimedes is equal to the mass of water displaced by the ice. Lets say the ice is x cm below the level of the water. then: force buoyancy = (density of water)*volume*gforce buoyancy = (density of water)*(area of ice cube)*x*g where g is the acceleration due to gravity equating this to the force of gravity gives: (density of water)*x = (density ice)*(total height of cube) hope that helps.
The answer depends on what you were trying to predict.

To measure density
It depends if the ice cube your talking about have the bigger density than the water which is 1.00G/ML then it will sink .... TO get the density of the cube u have u have to divide the mass over the volume of the cube..
Water has a density of 1 gram/cm3.
using pycnometry because the density of water is very accurate
