Answer:
285 Litre ( 1kg of water occupies 1 Litre )
which is identical to 285 dm^3 ie 285 cubes of length 10 cm
and as there are 10 of these linearly in 1 m then there are 10^3 = 1000 dm^3 in each m^3
giving a volume of 0.285 m^3
Of course if you KNEW that 1m^3 of water has a mass of 1000 kg then you would simply have said that the volume was 285/1000 m^3
The volume of the water will be 0.285 [tex]m^{3}[/tex]
A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes. Volume is the measure of the capacity that an object holds.
A method in which the value of the unit (one) quantity is first obtained to find the value of any required quantity is called the unitary method. So , by finding the value volume of 1 kg water , we can find the volume of 285 kg water by simply multiplying it with the volume of 1kg water using unitary method
using unitary method
1000 kg of mass have volume of = 1[tex]m^{3}[/tex]
then , the volume of 1kg will be = 1 / 1000 [tex]m^{3}[/tex]
The volume of 285 kg will be = (1 / 1000) * 285 = 0.285 [tex]m^{3}[/tex]
Hence if a barrel contains 285 kg of water, then the volume of the water will be 0.285 [tex]m^{3}[/tex]
