The density of liquid water is 1gram per cubic centimeter.
A cube 2*4*1 has a volume of 8 cubic centimeters. Thus if it is a cube of water it should have a mass of 8 grams.
As your cube has a mass of only 8 mg (that is 8 milligrams) the substance CAN NOT BE LIQUID WATER because it only has a density of .001grams per cubic centimeter.
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.
To measure the density of a liquid, a hydrometer is commonly used, which floats in the liquid and provides a reading based on the level it sinks to. For measuring the density of a large cube of metal, a balance scale can be used to determine its mass, while the volume can be calculated by measuring its dimensions or by water displacement in a graduated cylinder. The density is then calculated using the formula density = mass/volume.
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.
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.
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.
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.
Density = Mass/Volume = 8/(4*4*1) = 8/8 = 1 gram per cm3
The density of a cube of wood is determined by measuring its mass and volume. First, the mass is obtained using a scale, and then the volume is calculated by measuring the dimensions of the cube (length, width, and height) and applying the formula for the volume of a cube (V = side³). The density is then calculated using the formula: density = mass/volume. This gives the density in units like grams per cubic centimeter (g/cm³).
To measure the density of a liquid, a hydrometer is commonly used, which floats in the liquid and provides a reading based on the level it sinks to. For measuring the density of a large cube of metal, a balance scale can be used to determine its mass, while the volume can be calculated by measuring its dimensions or by water displacement in a graduated cylinder.

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 !
