That's bound to be a difficult operation, since there is no such unit.
Cubic meters and square meters aren't even the same kind of quantity.
Kilogram per cubic meter is the one that doesn't belong. Square meter is meter^2 and cubic meter is meter^3 but kilogram per cubic meter is a density
No, One cubic meter is 1m3 One square meter is 1m2
Impossible!!! Cubic meter is a volume measure and square meter is a measure of area!!!
if tank hight is 7mtr and dia is 8mtrs how i will calculate in cubic meter
