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 Route | Volume (cm3\text{cm}^3cm3) | Fluid Output Route | Volume (cm3\text{cm}^3cm3) |
|---|---|---|---|
| Intravenous (IV) saline | 1850 | Urine | 1420 |
| Oral fluids (drinks) | 650 | Insensible loss (breathing & skin) | 950 |
| Metabolic water | 280 | Gastrointestinal loss | VVV |
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.
