how many metric tonnes in a cubic meter
Best Answer: 1) Metric ton is 1000 kg. It is a unit of mass. Cubic metre is a unit of volume. 1 cubic metre of water weighs 1000 kg or 1 metric ton. 2) 1 cubic metre of sand weighs 1450 kg or 1.45 metric ton taking the specific gravity of sand as 1.45 (as stated in part 3 of the question).Hence 1 cubic meter of sand should cost US$ 7 x 1.45 = US$ 10.15.) 1 cubic metre of sand weighs 1450 kg or 1.45 metric ton taking the specific gravity of sand as 1.45 (as stated in part 3 of the question). Hence 1 cubic meter of sand should cost US$ 7 x 1.45 = US$ 10.15.
