Do you mean mass or weight?\n\nTo get the mass of 1 cubic meter of water:\n\nA cubic meter is a cube 1m x 1m x 1m \n\nConvert to centimeters this gives 100cm x 100 cm x 100cm\n\nTherefore the volumen of the cube in cubic cm is 1000000 cm3\n\n1 litre = 1000 cm3 therfore :\nvolume in litres is 1000000 / 1000 = 1000 l\n\nrelative density of water is 1kg / l therefore the mass of the water is 1000kg or 1 tonne.\n\nWeight is the gravitational force exerceted on the water by the earths gravitational pull. I'm assuming the water is stationary at ground level and not in orbit or something daft. The effect of gravity at ground level is given by the constant g which is 9.8N/kg.\n\nTherefore the weight of the water is 1000 * 9.8 =  9800N

I might be missing something, but the cubic space something occupies is also referred to as it volume, where:\n\nfor a six sides regular box shape volume = heightxbreadthx depth\n\n( make sure all your measurements are in feet eg 1 foot 5 inches is 1 and 5/12 feet. \n\nHowever this formula is not true for a sphere or a trapezoidal box or a pyramid.  For whcih I'd recommend wikipedia or the old maths textbook as its hmmm, err 18 years since I last did all that stuff.

let "a" be the side of the cube the volume of the cube will be a^3\nso V = (-9kx^3)^3\nV = - 729 k^3 x^9

The moment of inertia of an object is given as:\n\nI = volume integral of (r² dm)\n\n(I have no good way of writing this, so check the wikipedia link below of more info). Wikipedia also has a list of moments of inertia, which I've included below. It provides the moment of inertia for a disk as:\n\nI = (1/2) * M * R²\n\nAs for calculating it step by step, note that if the mass is evenly distributed throughout the disk, then the density of the disk is equal to its mass divided by its volume:\n\nrho = M / (pi * R² * h)\n\nThe infintesimal dm can be expressed as:\n\ndm = rho * dV\n\ndm = M / (pi * R² * h) * r * d-theta * dr * h\n\ndm = M / (pi * R²) * r * d-theta * dr\n\nThus, the moment of inertia is given as:\n\nI = int(int(M / (pi * R²) * r^3, r=0..R),theta=0..2pi)\n\n(again, I don't have a good way to express this - its a double integral of M / (pi * R²) * r^3 * dr * d-theta, where r goes from 0 to R and theta goes from 0 to 2pi). This reduces to:\n\nI = int(M / (pi * R²) * r^3 * 2pi, r=0..R)\n\nI = M/(pi * R²) * (1/4)*R^4 * 2pi\n\nI = M/(R²) * (1/2)*R^4\n\nI = (1/2) * M * R²\n\nSo that's how you find the moment of inertia. Now, substituting your values into this expression provides:\n\nI = (1/2)(41 kg) (18.8 cm * 1 m/100 cm)²\n\nI = .7246 kg-m²\n\nThat's it! :)

Determining the mass is trivial: just weigh the block.  For the density, you will need to know the volume, which will require some measuring with a ruler.  Then divide the mass by the volume for your answer.

To 'square' a number means to multiply it by itself.\nexample: 4 squared = 4 X 4\n\nTo 'cube' a number is to multiply it by itself again after squaring it.\nexample: 4 cubed = 4 X 4 X 4

Mass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.\n\n\nVolume is a quantification of how much space a certain region occupies. The international standard unit for volume is the cubic metre (American spelling: cubic meter). Volume should not be confused with capacity which is the maximum amount that a container can hold.\nThe volume of a solid object is a numerical value given to describe the three-dimensional concept of how much space it occupies. One-dimensional objects (such as lines) and two-dimensional objects (such as squares) are assigned zero volume in the three-dimensional space.\n\nDensity (symbol: ρ - Greek: rho) is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). The SI unit of density is the kilogram per cubic metre (kg/m3)  P=m/v\n \nwhere\n\nρ is the object's density (measured in kilograms per cubic meter) \nm is the object's total mass (measured in kilograms) \nV is the object's total volume (measured in cubic meters)

For moving objects, calculate kinetic energy using the formula:\nKE = (mass x velocity2)/2 or 1/2 mv2\n\nhttp://www.gmhsscience.com/problems/kineticpotential.htm

Not sure what you mean by linear, but linear acceleration can be described:  acceleration = force / mass\n\nArea of circle = pi r^2\n\nVolume of cube = length x width x height\n\nHope it helps

All is clear once you understand the difference between mass and weight.\n\nIf you are not sure, look here:

we know that mass = volume * density\nin the first case, mass = 278.1g\nvolume of the cube = 3*3*3 = 27 cm^3\ntherefore density = mass/ volume\n density of steel = 278.1/27 = 10.3\nThrefore the mass of 1 cm^3 of steel= volume * density\n                                    = 1 * 10.3\n                                    = 10.3 g\n\nNote: denstiy of any material is always a constant- it is an intrinsic property of the material. It is important to get these concepts right when you study them so that you can have a good foundation for higher studies. Please promise me that once you understand how to do this problem, you will try it on your own. Thanks. goodluck

In the front?  You have to consider the whole cube to find volume.  Volume = base area * height  You could find the surface area of one side, but you'd need to know the side length.

surface area of a cube is 6a^2\nvolume=a^3\ntheir relation: V/SA = a/6\n\nif its cut into half, volume will be:\n(a/2) x a^2 = (a^3) / 2\nthe surface area will be 2a^2 + 4a(a/2) = 4a^2\nnow their relation: V/SA = a/8\n\nnote: crazy horse's answer went wrong when he assumed a halved cube has only two of its sides halved. in fact, it has its 4 sides halved.

i will assume that you just asked how to find the mass of an object using a meter rule \nif that was the question it is simple\ntake the meter rule and hang it in such a way that it is in equilibrium i.e the scale is hanging horizontally\n\nknown hang the known mass on one side and hang the other mass on the other side\narrange in such a way that it is in equilibrium\nnow find the ditance of the known and the unknown mass from the position where the meter scale is tied and let it be a & b\n\nnow using the Principle Of Moments\n\nM*a=m*b\n\nhope it was helpful

If we consider the volume of water is known.(If not known then use graduated cylinder and find the volume)\nMass of water can be calculated using following formula:\n\nDensity(ρ)=mass(m)/volume(V) , where\nρ is the object's density (measured in kilograms per cubic meter) \nm is the object's total mass (measured in kilograms) \nV is the object's total volume (measured in cubic meters) \n(Temp (°C)/ Density (g/cm3) \n30/ 0.9957 \n20 /0.9982 \n10 /0.9997 \n0 /0.9998 \n−10/ 0.9982 \n−20 /0.9935 \n−30/ 0.9839 )
