This question cannot be answered in a sensible way. A cubic metre is a measure of volume, with dimensions [L3]. A tonne is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information. Just think of the volumes occupied by a tonne of lead and a tonne of air.

There is no such thing as a "cubic ton". You can have cubic meters, but not cubic tons.
To convert cubic meters of asphalt to tons, you need to know the density of the asphalt, which typically ranges from about 2,200 to 2,400 kg/m³. Multiply the volume in cubic meters by the density to get the mass in kilograms, then divide by 1,000 to convert to tons. For example, if the density is 2,300 kg/m³, then 1 cubic meter of asphalt would equal approximately 2.3 tons.
The answer will depend on what metal the ore contains.
One cubic yard of broken limestone weighs about 1.3 tons. One cubic yard of pulverized limestone weighs about 1.17 tons.
-- 1 cubic meter of space is 1,000 liters of space. -- 1 liter of water has 1 kilogram of mass. -- 1,000 liters of water has 1,000 kilograms of mass = 1 metric ton -- 1 metric ton of water fills 1 cubic meter of space. -- A substance with a specific gravity of 2.7 packs 2.7 times as much mass into the same space. -- 2.7 metric tons of it pack into 1 cubic meter of space. -- The number of cubic meters it occupies is (the number of metric tons)/2.7 . -- For ANY substance, the number of cubic meters it fills is (the # of metric tons)/(specific gravity) .
