Maybe the dividing slash has been omitted and it should read kg/m3, that is kilograms per cubic meter
P=hdg 100*1150*10=1150000Pa
Convert: 1kg/m3 to g/cm3 1kg=1000g 1m3=100*100*100=1000000cm3 therefore: 1000g/1000000cm3 = 0.001g/cm3 4200kg/m3 * 0.001g/cm3 = 4.2g/cm3
You can solve this in two steps. (1) Calculate the ball's volume. Use the formula for a sphere, and remember that the radius is 1/2 the diameter. Convert the result it either to cubic decimeters (= liters) or to cubic meters. (2) Divide the mass by the volume.
The average density of granite is 2.75 g/cm3.
Let us formulate the formula. If suppose m is the mass of the body then mg will be the force acting on it due to gravity. If d is the density and v the volume then v d will be the mass. Hence the force due to gravity will become v d g. This force acting due to gravity is other wise known as weight of the body. Now in your problem note down the unit. It has to be in SI system. Unit for volume is m3 and that for density is kg m-3. The unit for g is m/s2 Hence as per your problem, simply multiply 0.08, 7840 and 9.8. You will get the required answer.
I think you mean how much is MegaPascal in kg/m2 (not kgm3) Answer : 1 MP = 101971.6 kg/m2
The volume is 5m3 density=1,200 kgm3 what is the mass
11995 kgm3
7850 kg/m3
density
1000grams in a kilogram.
1 gram/centimeter3 (g/cm3) equals 1000 kilogram/meter3 (kg/m3)
P=hdg 100*1150*10=1150000Pa

1. The density of mercury is 13 534 kg/m3.2. Mercury sink in water.
It is 352000 kg/m^3. This is absurdly dense: Osmium, the most dense element on earth has a density of 22.6 g/cm^3 - less than a fifteenth of your substance.
There are 1000 kg in a metric ton. As such 1m3 of concrete of density 2400 kg/m3 has a mass of 2.4 metric tons.
