Given a total body water of 48 L, extracellular fluid is approximately what volume?

Explanation:
Extracellular fluid is about one third of total body water. With total body water at 48 L, the extracellular fluid would be approximately 48 L × 1/3 = 16 L. The remaining two thirds make up intracellular fluid (about 32 L). Extracellular fluid consists of plasma and interstitial fluid, which together typically sum to around this one-third value, though exact amounts can vary slightly between individuals.
