In a homogeneous unconfined aquifer of area 3.00 km2, the water table was at an elevation of 102.00 m. After a natural recharge of volume 0.90 million cubic meter (Mm3) the water table rose to 103.20 m. After this recharge, groundwater pumping took place and the water table dropped down to 101.20 m. The volume of groundwater pumped after the natural recharge, expressed (in Mm3 and round off to two decimal places), is _______.
