In clinical medicine, monitoring a patient's fluid balance is critical to prevent dehydration or fluid overload. A patient on an intensive care ward has their fluid intake and output monitored over a 24-hour period.

The table below shows the recorded volumes for each route of fluid gain and loss.

Fluid Input RouteVolume (cm3\text{cm}^3cm3)Fluid Output RouteVolume (cm3\text{cm}^3cm3)
Intravenous (IV) saline1850Urine1420
Oral fluids (drinks)650Insensible loss (breathing & skin)950
Metabolic water280Gastrointestinal lossVVV

During this 24-hour period, the patient's net fluid balance was positive, resulting in a net retention of 120 cm3 of water in their body.

Calculate the volume of water, VVV, lost via gastrointestinal loss.
