The question, as stated, cannot be answered sensibly. A cubic metre is a measure of volume, with dimensions [L3]. A metre is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
What do you want to convert it to? 15 liters is the same as 15 cubic decimeters, or 0.015 cubic meters.
12*15*0.1=18 18 cubic meters
15
85.5 square meters times 0.05 meters is a volume of 4.275 cubic meters.
1.68 cubic meters
360 cubic meters is 360,000,000cc
419,328 cubic inches is 6.871 cubic meters.
1 gallon = 0.003785 cubic meters
Does not convert. Cubic meters is volume and square meters is area.
15x1000 is 15,000 litres (x1000 from m3 to litres)
One liter is 0.001 (1/1000th) cubic meters.
10 cubic meters = 10,000 liters
