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.
To find the mass of a metal cube, you can use a balance scale. Simply place the cube on the scale, and it will provide the mass directly in grams or kilograms. Alternatively, if you know the density of the metal, you can calculate the mass by measuring the cube's volume (length × width × height) and using the formula: mass = density × volume.
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.
The relative density of a plastic cube is the ratio of the density of the plastic cube to the density of water. To calculate it, you would divide the density of the plastic cube by the density of water (usually 1 g/cm^3). If the relative density is less than 1, the cube will float in water, and if it's greater than 1, the cube will sink.
The cube of water would have a greater density because it has a mass of 1g in a smaller volume of 1 cm³, resulting in a density of 1 g/cm³. The block of plastic has a mass of 4g in a larger volume of 6 cm³, resulting in a density of 0.67 g/cm³.
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.
The density of the floating cube is equal to the density of the fluid it is floating in. This is because the cube is in equilibrium, meaning the weight of the cube is equal to the weight of the fluid it displaces. Therefore, its density is the same as the fluid's 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.
The answer depends on what you were trying to predict.
-- 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 !
Density=mass per volume =1g/cm cube density of 170mL water=170g per 170mL =1g/cm cube
To measure density
The density of water is 1 g/cm³. So, the volume of the cube of water would be equal to its mass divided by its density, which is 512g / 1 g/cm³ = 512 cm³.
