There can be no equivalence.
A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.

One cubic meter equates to 61,023.74 cubic inches.
There are 1003 , or 1000000 cubic cm in one cubic meter.
one cubic meter is 35.3 cubic feet
A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
The only way to solve this is to identify the substance being measured. For example, exactly one cubic meter of pure water at sea level, at a temperature of 3.98 °C (its densest) masses exactly 1,000 kilograms, or one metric tonne. (In fact, this is the very definition of a metric tonne.)
