If you are given the volume, then you do not need to work it out!
Kilograms are a measure of mass, not volume. The volume of a given mass would depend upon the density of the substance.
This can not be worked out as volume is bassically a measure of size and so you need the dimensions to work this out, however if you mean density than you can not work that out without knowing the weight and volume.
We measure pitch with frequency and volume with amplitude.
With the information given in the question, the only answer that I can offer is that you measure it, using a protractor.
A litre is a measure of volume. Calculation of a volume requires 3 linear measures: length, breadth and depth. It appears that you have given only two.
Tonnes do not measure volume.

Density

The mass of a substance in unit volume is its density.
density
measure it
This is referred to as 'volume'.
Directly, they are not as the measure different properties.Combining them can give you the density of a substance. Which is the mass of a given substance in a given volume.
Assuming you can't work it out mathematically, fully submerge the object in a container filled to the top with water, then measure the volume of the water displaced.
Density aka specific gravity is a measure of the amount of matter in a given volume. Actually specific gravity is not the measure of the amount of matter in a given value, it is a comparison of the density of the substance to water's density. Specific gravity is a unitless quantity.
measure the volume of liquid that the object displaces
