the density of an object that is 10 cm by 2 cm and has a mass 400g will be 10000 Kg m-3.
This can be calculated by the formula, density = mass/volume
Density is the amount of matter per cubic unit. So, in order to find density, you need to divide the mass of the object by its volume. For an example: if a rock has a volume of 2 cubic meters and it has a mass of 10 kg., then you would divide 10 by 2 and you get the density of the rock (i.e., 5 kg/meter^3). Density = Mass / Volume
For solids that are not soluble or reactive in/to water.Density = Mass (g) / Volume (mL)first find the weight of the solid in grams on a scale. (Mass)second fill a beaker or other liquid measuring apparatus, large enough to hold the solid, with water (DI is best)third take note of the amount of liquid in the container (preferably in mL)forth fully submerge the solid in the liquid and note the new amount of liquid in the container.now subtract the first amount of liquid from the second. this will give the volume of the object (Volume)Density = Mass/Volume D= M/V D= g/mL
By Archimedes' Principle, a floating body displaces a volume of fluid whose weight is exactly equal to its own.This assumes that the body is in equilibrium.In order to know the weight of the body (i.e. the object) you must know the density of the fluid in which it is floating.Also, Surface Area (SA, in cm2) of object must be known.Suppose density of the fluid is rho.Thus, Having height = 10cmWobject = Volumedisplaced*Densityfluid = SA*Height*rhoSuppose it is water with rho = 1g/cm3, SA = 1cm2Wobject = 10cm*1cm2*1g/cm3 = 10g.Just make sure your units are correct.
If you do the math, the Formula for Density is Mass / Volume. Density = Mass Volume Density = 50 5 Density = 10 g/ml Therefore your density of the cube is 10g/ml ... 99.99% sure this is the correct formula and solution. Hope this helps. :)
Weight assuming your talking about the force pulling us to the ground is measured in newtons. To find out the amount of newtons an object has you measure its mass(kilograms,grams etc.) and multiply its mass by 10. Example if a book had a mass of 1kg its weight is 10N.
The object's density is 10 g/cm3
The density of the object is 5 g/mL

3 g/10 cm3 = 0.3 g/cm3 and this is the density, since density is expressed as mass/volume.
The 50g one does have the greater density. This is because density is defined as mass divided by volume.
density = mass/volume density = 5/10 = 0.5 grams per cubic centimeter
Since density = mass/volume, D = 25/10 = 2.5g/cm^3
Density = mass/milliliters Density = 10 grams/2 ml = 5 g/ml ---------------
density = mass ÷ volume = 30 g ÷ 10 cm3 = 3 g/cm3
Density is 2 kg/mL
The object's density is 5 g/mL
